The CData Sync App provides a straightforward way to continuously pipeline your Microsoft Excel Online data to any database, data lake, or data warehouse, making it easily available for Analytics, Reporting, AI, and Machine Learning.
The Microsoft Excel Online connector can be used from the CData Sync application to pull data from Microsoft Excel Online and move it to any of the supported destinations.
The Sync App supports connecting to Excel Services via SharePoint Online, which is supported by the Microsoft Graph API. It models spreadsheets and ranges as bidirectional tables.
For required properties, see the Settings tab.
For connection properties that are not typically required, see the Advanced tab.
There are two authentication methods available for connecting to Microsoft Excel Online data source:
Azure AD is user-based authentication. Credentials are supplied to connect AzureAD to Microsoft Excel Online via a Desktop application. To use the embedded credentials for authentication, leave the OAuth credentials (OAuthClientId and OAuthClientSecret) blank.
For connecting via a Web application, you must create a custom OAuth Azure AD application. The creation of a Custom Azure AD application establishes the OAuth credentials OAuthClientId and OAuthClientSecret. For a discussion of how to create a custom Azure AD application, and reasons why that might be advantageous even if you are not connecting via a Web application, see Creating an Azure AD Application.
The authentication as an Azure Service Principal is handled via the OAuth Client Credentials flow. It does not involve direct user authentication. Instead, credentials are created for just the application itself. All tasks taken by the app are done without a default user context, but based on the assigned roles. The application access to the resources is controlled through the assigned roles' permissions.
Create an AzureAD App and an Azure Service Principal
When authenticating using an Azure Service Principal, you must create and register an Azure AD application with an Azure AD tenant. See Creating an Azure AD Application for more details.
In your App Registration in portal.azure.com, navigate to API Permissions and select the Microsoft Graph permissions. There are two distinct sets of permissions: Delegated permissions and Application permissions. The permissions used during client credential authentication are under Application Permissions.
Assign a role to the application
To access resources in your subscription, you must assign a role to the application.
Client Secret
Set these connection properties:
Certificate
Set these connection properties:
You are now ready to connect. Authentication with client credentials takes place automatically like any other connection, except there is no window opened prompting the user. Because there is no user context, there is no need for a browser popup. Connections take place and are handled internally.
If you are running Microsoft Excel Online on an Azure VM and want to automatically obtain Managed Service Identity (MSI) credentials to connect, set AuthScheme to AzureMSI.
If your VM has multiple user-assigned managed identities, you must also specify OAuthClientId.
The Sync App exposes workbooks and worksheets from drives you specify in your Microsoft account. You can connect to a workbook by providing authentication to Excel Online and setting any of the following properties.
To control which drives are discovered:
If none of the above are specified, access is restricted to the authenticated user's personal drive.
To control which workbooks and worksheets are exposed OR which drives are exposed:
For information on how to execute data manipulation SQL against worksheets and ranges, see:
For details on how the Sync App models worksheets and cells as tables and columns, See Data Model.
SharepointURL=https://mysite.sharepoint.com/The driver automatically looks up each document library you have in SharePoint and lists it as a schema. Individual Excel workbooks and worksheets are listed as tables in the format Workbook_Worksheet under their corresponding document library. This works in the same manner as listing your own personal Excel documents when SharepointURL is not set.
The following connection properties enable you to execute SELECT queries that closely match how your sheet is organized.
SELECT Id, Name, Item, Quantity, Amount FROM Test_xlsx_Sheet1 WHERE Amount = 50The query above assumes that the first row of the worksheet has the column names Id, Name, Quantity, and Amount. The worksheet may have more columns than were selected and they can be in any order.
SELECT A, B, C, D FROM Test_xlsx_Sheet1 WHERE D = 50
To select a range of data on the worksheet, append the range to the table name with the # character. For example, the following command will select the range of cells between A1 and E5:
SELECT * FROM Test_xlsx_Sheet1#A1:E5
To assign a table name to a range, and avoid specifying the range repeatedly, see the Tables property.
You can execute INSERT statements when working with worksheets as tables. You can specify the column names detected from a header row or specify the alphabetical column names in Excel Online. You can also configure how the Sync App parses the input values into Microsoft Excel Online cell formats.
Set the Header property to configure column names. Set ValueInputOption to configure input parsing.
Note that inserting to ranges is not supported. Use Batch Inserts or Temporary Tables instead.
When the Header property is set to true, you can specify cells in a header row as the column names.
INSERT INTO Test_xlsx_Sheet1 (Name, Amount) VALUES ('Test', 10)
When the Header property is set to false, provide the alphabetical column names.
INSERT INTO Test_xlsx_Sheet1 (A, B) VALUES ('Test', 10)
By default, the Sync App parses all values you input in the SQL statement the same as if you entered the input in the Microsoft Excel Online UI. For example, strings may be converted to numbers, dates, etc.
To disable the parsing of input values, set ValueInputOption. Additionally, see Using Formulas to configure formula evaluation.
If using temporary tables, they must be defined and inserted within the same connection. Closing the connection will clear out any temporary tables in memory.
Insert the rows you need in a temporary table. Then insert all the rows from that temporary table into the actual table.
In UPDATE statements, you can specify the column names detected from a header row or specify the alphabetical column names in Microsoft Excel Online. You can also configure how the Sync App parses the input values into Microsoft Excel Online cell formats.
Set the Header property to configure column names. The primary key is the row number; specify the primary key with the Id column. Set ValueInputOption to configure input parsing.
When the Header property is set to true, you update columns by specifying the detected column names.
UPDATE Customers SET Col1='value' WHERE Id=7
When the Header is set to false, provide the alphabetical column names:
UPDATE Customers SET H='value' WHERE Id=7
Set the columns corresponding to the range and specify the row number as the Id:
UPDATE [Customers#A15:C15] SET A='Ana Trujilo', B='Northwind, Inc.', C='100,000' WHERE Id='15'
By default, the Sync App parses all values you input in the SQL statement the same as if you entered the input in the Microsoft Excel Online UI. For example, strings may be converted to numbers, dates, etc.
To disable the parsing of input values, set ValueInputOption. Additionally, see Using Formulas to configure formula evaluation.
When deleting an entire row of data, you will need to be sure to refresh the table data. This is because Ids are assigned based on the row. For example, if there are five rows, with Ids 1 through 5, and you delete row 3 then row 4 will become 3 and 5 will become 4.
Set the following properties to configure formula evaluation when executing SELECT, INSERT, and UPDATE statements.
The Sync App can return either the result of the formula or the formula itself; configure this behavior with the ValueRenderOption connection property.
Set AllowFormula to true to insert formulas (the default). Otherwise, all values used in inserts and updates are inserted as string literals.
For example, with AllowFormula set to true, the following will insert a formula into the B column that will sum cells B1:B5:
INSERT INTO Excel_Sheet (A, B) VALUES ('Bill', '=SUM(B1:B5)')
Note: If AllowFormula is set to true, every column containing a formula will be exposed as String type regardless of the set TypeDetectionScheme.
This section details a selection of advanced features of the Microsoft Excel Online Sync App.
The Sync App supports the use of user defined views, virtual tables whose contents are decided by a pre-configured user defined query. These views are useful when you cannot directly control queries being issued to the drivers. For an overview of creating and configuring custom views, see User Defined Views .
Use SSL Configuration to adjust how Sync App handles TLS/SSL certificate negotiations. You can choose from various certificate formats;. For further information, see the SSLServerCert property under "Connection String Options" .
Configure the Sync App for compliance with Firewall and Proxy, including Windows proxies and HTTP proxies. You can also set up tunnel connections.
For further information, see Query Processing.
By default, the Sync App attempts to negotiate TLS with the server. The server certificate is validated against the default system trusted certificate store. You can override how the certificate gets validated using the SSLServerCert connection property.
To specify another certificate, see the SSLServerCert connection property.
To authenticate to an HTTP proxy, set the following:
Set the following properties:
The Sync App models the worksheets and ranges in your workbooks as bidirectional tables. When you connect, the Sync App retrieves the metadata from Microsoft Excel Online and reflects any changes to the table schemas.
See the Getting Started section for quickstarts to executing SQL to the tables. This section provides additional details on the Sync App behavior.
This section provides more detail about how the Sync App models the Tables. See Columns for details about column discovery.
Query the available System Tables to access the available Sync App metadata, including schema information.
1) If you currently have many workbooks or sheets in your account, it may take a long time to initially retrieve all the data. You may shorten this time by adding the Workbook connection property to your connection string.
2) If you will be running a SELECT operation after INSERT or BATCH INSERT then make sure to wait 3-5 seconds before running it. The API takes a few seconds to register all the data you're adding to the database, so waiting is required to avoid partial results.
The Sync App exposes worksheets from workbooks as tables. To do so, it exposes the drives containing these workbooks and worksheets as schemas for these tables. How drives are exposed as schemas is dependent on the connection propeties for the Sync App.
The following connection properties determine what drives are exposed as schemas by the driver. They are listed in order of precedence, where only the most precedent property is used to expose schemas:
You can use the Drives and SharePointSites views to view all the sites and drives you have access to.
If you would like to filter the schemas the driver exposes, you can use, the BrowsableSchemas connection property. Supply a list of drive names to this property. The filtering is done client-side, so this means that the names supplied should be the names that would normally be returned by the Sync App for the drives.
The Sync App enables you to represent a top-left-oriented worksheet or a user-specified range as a database table.
You can execute SELECT or UPDATE commands against a given range with a reference in the following format: WORKSHEET#RANGE. You can also set the Tables property to assign a table name to a range.
For example, the following command will select the range of cells between A1 and E5:
SELECT * FROM Test_xlsx_Sheet1#A1:E5
You can use the connection property ShowSharedDocuments to list shared excel workbooks as database tables. The tables will be listed along-side user owned workbooks.
See the following to execute data manipulation SQL to worksheets and ranges:
When you connect, the Sync App discovers the available columns and reflects both changes in Microsoft Excel Online and configuration changes you make with the following connection properties. See the following sections to configure aspects of column discovery specific to Microsoft Excel Online.
You can set Header to detect column names in a header row or you can reference columns alphabetically.
Below are more specifics on how the Sync App detects column names from a header row when Header is set to true.
When Header is set to false, alphabetical column names will be dynamically assigned.
The Sync App reports the row number as the primary key. The Id column for each row represents the row number from the top of the sheet.
For example, if you specify a range A3:E6, rows 3, 4, 5, and 6 will be returned.
The ValueRenderOption and ValueInputOption connection properties can be used to configure how the Sync App parses the Microsoft Excel Online cell formats in SELECT, INSERT and UPDATE operations.
Set the ValueRenderOption to configure how the Sync App renders values in the output of a SELECT operation. The available value render options are as below.
Set the ValueInputOption to configure how the Sync App parses values the user submits to the Microsoft Excel Online source for INSERT and UPDATE operations. The available value input options are as below.
Set the TypeDetectionScheme to configure the data type detection method. The available type detection schemes are as below.

| Property | Description |
| DefineTables | Assign table names to ranges. |
| Workbook | The name or Id of the workbook. |
| Drive | The Id of the drive. |
| IncludeSharePointSites | Whether to retrieve drives for all SharePoint sites when querying Drives view. If 'true' the provider will retrieve all Site IDs recursively and for each of them issue a separate call to get their drives. Therefore, be aware that setting this property to 'true' may decrease performance for the Drives view. Note that the SharePointAccessToken or OAuthJWTCert connection property must be specified to query the SharePointSites view and other views if IncludeSharePointSites is set to 'true' when using the CLIENT OAuthGrantType or the AzureServicePrincipal AuthScheme. |
Assign table names to ranges.
This property is used to define the ranges within a worksheet that will appear as tables. The value is a semicolon-separated list of name-value pairs in the form [Table Name]=[Catalog].[Schema].[{Workbook Name}_{Worksheet Name}!{Range}]. The value can also be specified in the form [Table Name]=[{Workbook Name}_{Worksheet Name}!{Range}]. Note that in this case, the driver will attempt to push the defined table for each schema it identifies, should the specified workbook and worksheet exist in the schema. For specifications of DefineTables, some characters, like ., are reserved characters. To escape these characters and make sure that the name containing them is parsed properly, surround the containing name with brackets, as in [work.book_work.sheet!A1:Z50]. For this example, the driver would properly search for the workbook and worksheet identified by work.book_work.sheet, despite the specification containing reserved characters.
Here is an example DefineTables value:
DefineTables="Table1=Test_xlsx_Sheet1!A1:N25,Table2=[CData].[MySchema].[Spreadsheet1_Sheet2!C3:M53],Table4=xIsPcLs2-bF3AavQcSLCfzs3kGc_Sheet4!C20:N60"
After setting DefineTables, you can then issue queries that reference the specified table name. Note that you can also use the range syntax directly in the SQL statement: append the range to the worksheet name with the # character.
For example, the following command will select the range of cells between A1 and E5:
SELECT * FROM Test_xlsx_Sheet1#A1:E5
The name or Id of the workbook.
Specifies the name or Id of the workbook. A list of all workbooks is available from the Workbooks view.
The Id of the drive.
Specifies the Id of the drive. A list of all drives is available from the Drives view. This property takes precedence over SharepointURL. This means that if SharepointURL and Drive are specified, a schema will only be identified for the drive specified by Drive, and tables will only be identified from the worksheets in workbooks in this drive.

This section provides a complete list of the Firewall properties you can configure in the connection string for this provider.
| Property | Description |
| FirewallType | Specifies the protocol the provider uses to tunnel traffic through a proxy-based firewall. |
| FirewallServer | Identifies the IP address, DNS name, or host name of a proxy used to traverse a firewall and relay user queries to network resources. |
| FirewallPort | Specifies the TCP port to be used for a proxy-based firewall. |
| FirewallUser | Identifies the user ID of the account authenticating to a proxy-based firewall. |
| FirewallPassword | Specifies the password of the user account authenticating to a proxy-based firewall. |
Specifies the protocol the provider uses to tunnel traffic through a proxy-based firewall.
A proxy-based firewall (or proxy firewall) is a network security device that acts as an intermediary between user requests and the resources they access. The proxy accepts the request of an authenticated user, tunnels through the firewall, and transmits the request to the appropriate server.
Because the proxy evaluates and transfers data backets on behalf of the requesting users, the users never connect directly with the servers, only with the proxy.
Note: By default, the Sync App connects to the system proxy. To disable this behavior and connect to one of the following proxy types, set ProxyAutoDetect to false.
The following table provides port number information for each of the supported protocols.
| Protocol | Default Port | Description |
| TUNNEL | 80 | The port where the Sync App opens a connection to Microsoft Excel Online. Traffic flows back and forth via the proxy at this location. |
| SOCKS4 | 1080 | The port where the Sync App opens a connection to Microsoft Excel Online. SOCKS 4 then passes theFirewallUser value to the proxy, which determines whether the connection request should be granted. |
| SOCKS5 | 1080 | The port where the Sync App sends data to Microsoft Excel Online. If the SOCKS 5 proxy requires authentication, set FirewallUser and FirewallPassword to credentials the proxy recognizes. |
To connect to HTTP proxies, use ProxyServer and ProxyPort. To authenticate to HTTP proxies, use ProxyAuthScheme, ProxyUser, and ProxyPassword.

This section provides a complete list of the Proxy properties you can configure in the connection string for this provider.
| Property | Description |
| ProxyAutoDetect | Specifies whether the provider checks your system proxy settings for existing proxy server configurations, rather than using a manually specified proxy server. |
| ProxyServer | The hostname or IP address of the proxy server that you want to route HTTP traffic through. |
| ProxyPort | The TCP port on your specified proxy server (set in the ProxyServer connection property) that has been reserved for routing HTTP traffic to and from the client. |
| ProxyAuthScheme | Specifies the authentication method the provider uses when authenticating to the proxy server specified in the ProxyServer connection property. |
| ProxyUser | The username of a user account registered with the proxy server specified in the ProxyServer connection property. |
| ProxyPassword | The password associated with the user specified in the ProxyUser connection property. |
| ProxySSLType | The SSL type to use when connecting to the proxy server specified in the ProxyServer connection property. |
| ProxyExceptions | A semicolon separated list of destination hostnames or IPs that are exempt from connecting through the proxy server set in the ProxyServer connection property. |
Specifies whether the provider checks your system proxy settings for existing proxy server configurations, rather than using a manually specified proxy server.
When this connection property is set to True, the Sync App checks your system proxy settings for existing proxy server configurations (no need to manually supply proxy server details).
This connection property takes precedence over other proxy settings. Set to False if you want to manually configure the Sync App to connect to a specific proxy server.
To connect to an HTTP proxy, see ProxyServer. For other proxies, such as SOCKS or tunneling, see FirewallType.
The hostname or IP address of the proxy server that you want to route HTTP traffic through.
The Sync App only routes HTTP traffic through the proxy server specified in this connection property when ProxyAutoDetect is set to False. If ProxyAutoDetect is set to True, which is the default, the Sync App instead routes HTTP traffic through the proxy server specified in your system proxy settings.
The TCP port on your specified proxy server (set in the ProxyServer connection property) that has been reserved for routing HTTP traffic to and from the client.
The Sync App only routes HTTP traffic through the proxy server port specified in this connection property when ProxyAutoDetect is set to False. If ProxyAutoDetect is set to True, which is the default, the Sync App instead routes HTTP traffic through the proxy server port specified in your system proxy settings.
For other proxy types, see FirewallType.
Specifies the authentication method the provider uses when authenticating to the proxy server specified in the ProxyServer connection property.
The authentication type can be one of the following:
For all values other than "NONE", you must also set the ProxyUser and ProxyPassword connection properties.
If you need to use another authentication type, such as SOCKS 5 authentication, see FirewallType.
The username of a user account registered with the proxy server specified in the ProxyServer connection property.
The ProxyUser and ProxyPassword connection properties are used to connect and authenticate against the HTTP proxy specified in ProxyServer.
After selecting one of the available authentication types in ProxyAuthScheme, set this property as follows:
| ProxyAuthScheme Value | Value to set for ProxyUser |
| BASIC | The user name of a user registered with the proxy server. |
| DIGEST | The user name of a user registered with the proxy server. |
| NEGOTIATE | The username of a Windows user who is a valid user in the domain or trusted domain that the proxy server is part of, in the format user@domain or domain\user. |
| NTLM | The username of a Windows user who is a valid user in the domain or trusted domain that the proxy server is part of, in the format user@domain or domain\user. |
| NONE | Do not set the ProxyPassword connection property. |
The Sync App only uses this username if ProxyAutoDetect is set to False. If ProxyAutoDetect is set to True, which is the default, the Sync App instead uses the username specified in your system proxy settings.
The password associated with the user specified in the ProxyUser connection property.
The ProxyUser and ProxyPassword connection properties are used to connect and authenticate against the HTTP proxy specified in ProxyServer.
After selecting one of the available authentication types in ProxyAuthScheme, set this property as follows:
| ProxyAuthScheme Value | Value to set for ProxyPassword |
| BASIC | The password associated with the proxy server user specified in ProxyUser. |
| DIGEST | The password associated with the proxy server user specified in ProxyUser. |
| NEGOTIATE | The password associated with the Windows user account specified in ProxyUser. |
| NTLM | The password associated with the Windows user account specified in ProxyUser. |
| NONE | Do not set the ProxyPassword connection property. |
For SOCKS 5 authentication or tunneling, see FirewallType.
The Sync App only uses this password if ProxyAutoDetect is set to False. If ProxyAutoDetect is set to True, which is the default, the Sync App instead uses the password specified in your system proxy settings.
The SSL type to use when connecting to the proxy server specified in the ProxyServer connection property.
This property determines when to use SSL for the connection to the HTTP proxy specified by ProxyServer. You can set this connection property to the following values :
| AUTO | Default setting. If ProxyServer is set to an HTTPS URL, the Sync App uses the TUNNEL option. If ProxyServer is set to an HTTP URL, the component uses the NEVER option. |
| ALWAYS | The connection is always SSL enabled. |
| NEVER | The connection is not SSL enabled. |
| TUNNEL | The connection is made through a tunneling proxy. The proxy server opens a connection to the remote host and traffic flows back and forth through the proxy. |
A semicolon separated list of destination hostnames or IPs that are exempt from connecting through the proxy server set in the ProxyServer connection property.
The ProxyServer is used for all addresses, except for addresses defined in this property. Use semicolons to separate entries.
Note that the Sync App uses the system proxy settings by default, without further configuration needed. If you want to explicitly configure proxy exceptions for this connection, set ProxyAutoDetect to False.
This section provides a complete list of the Logging properties you can configure in the connection string for this provider.
| Property | Description |
| LogModules | Specifies the core modules to include in the log file. Use a semicolon-separated list of module names. By default, all modules are logged. |
Specifies the core modules to include in the log file. Use a semicolon-separated list of module names. By default, all modules are logged.
This property lets you customize the log file content by specifying the logging modules to include. Logging modules categorize logged information into distinct areas, such as query execution, metadata, or SSL communication. Each module is represented by a four-character code, with some requiring a trailing space for three-letter names.
For example, EXEC logs query execution, and INFO logs general provider messages. To include multiple modules, separate their names with semicolons as follows: INFO;EXEC;SSL.
The Verbosity connection property takes precedence over the module-based filtering specified by this property. Only log entries that meet the verbosity level and belong to the specified modules are logged. Leave this property blank to include all available modules in the log file.
For a complete list of available modules and detailed guidance on configuring logging, refer to the Advanced Logging section in Logging.
This section provides a complete list of the Schema properties you can configure in the connection string for this provider.
| Property | Description |
| Location | Specifies the location of a directory containing schema files that define tables, views, and stored procedures. Depending on your service's requirements, this may be expressed as either an absolute path or a relative path. |
| BrowsableSchemas | Optional setting that restricts the schemas reported to a subset of all available schemas. For example, BrowsableSchemas=SchemaA,SchemaB,SchemaC . |
| Tables | Optional setting that restricts the tables reported to a subset of all available tables. For example, Tables=TableA,TableB,TableC . |
| Views | Optional setting that restricts the views reported to a subset of the available tables. For example, Views=ViewA,ViewB,ViewC . |
Specifies the location of a directory containing schema files that define tables, views, and stored procedures. Depending on your service's requirements, this may be expressed as either an absolute path or a relative path.
The Location property is only needed if you want to either customize definitions (for example, change a column name, ignore a column, etc.) or extend the data model with new tables, views, or stored procedures.
If left unspecified, the default location is %APPDATA%\\CData\\ExcelOnline Data Provider\\Schema, where %APPDATA% is set to the user's configuration directory:
| Platform | %APPDATA% |
| Windows | The value of the APPDATA environment variable |
| Linux | ~/.config |
Optional setting that restricts the schemas reported to a subset of all available schemas. For example, BrowsableSchemas=SchemaA,SchemaB,SchemaC .
Listing all available database schemas can take extra time, thus degrading performance. Providing a list of schemas in the connection string saves time and improves performance.
Optional setting that restricts the tables reported to a subset of all available tables. For example, Tables=TableA,TableB,TableC .
Listing all available tables from some databases can take extra time, thus degrading performance. Providing a list of tables in the connection string saves time and improves performance.
If there are lots of tables available and you already know which ones you want to work with, you can use this property to restrict your viewing to only those tables. To do this, specify the tables you want in a comma-separated list. Each table should be a valid SQL identifier with any special characters escaped using square brackets, double-quotes or backticks. For example, Tables=TableA,[TableB/WithSlash],WithCatalog.WithSchema.`TableC With Space`.
Note: If you are connecting to a data source with multiple schemas or catalogs, you must specify each table you want to view by its fully qualified name. This avoids ambiguity between tables that may exist in multiple catalogs or schemas.
Optional setting that restricts the views reported to a subset of the available tables. For example, Views=ViewA,ViewB,ViewC .
Listing all available views from some databases can take extra time, thus degrading performance. Providing a list of views in the connection string saves time and improves performance.

For example, Views=ViewA,[ViewB/WithSlash],WithCatalog.WithSchema.`ViewC With Space`.
Note: If you are connecting to a data source with multiple schemas or catalogs, you must specify each view you want to examine by its fully qualified name. This avoids ambiguity between views that may exist in multiple catalogs or schemas.
This section provides a complete list of the Miscellaneous properties you can configure in the connection string for this provider.
| Property | Description |
| AllowFormula | Whether or not to treat values starting with an equals (=) sign as formulas during inserts and updates. |
| Header | Indicates whether or not the provider should detect column names from the first row. |
| MaxRows | Specifies the maximum rows returned for queries without aggregation or GROUP BY. |
| Other | Specifies additional hidden properties for specific use cases. These are not required for typical provider functionality. Use a semicolon-separated list to define multiple properties. |
| Pagesize | The maximum number of results to return per page from Microsoft Excel Online when UsePagination is True. |
| PseudoColumns | Specifies the pseudocolumns to expose as table columns. Use the format 'TableName=ColumnName;TableName=ColumnName'. The default is an empty string, which disables this property. |
| RowScanDepth | The maximum number of rows to scan to look for the columns available in a table. |
| SharepointURL | The base URL of your Sharepoint Server. |
| ShowSharedDocuments | Whether or not to show shared documents. |
| Timeout | Specifies the maximum time, in seconds, that the provider waits for a server response before throwing a timeout error. The default is 60 seconds. Set to 0 to disable the timeout. |
| TypeDetectionScheme | Determines the method for identifying the data types of columns. |
| UsePagination | Whether or not the CData ADO.NET Provider for Microsoft Excel Online should use client side paging. |
| UserDefinedViews | Specifies a filepath to a JSON configuration file defining custom views. The provider automatically detects and uses the views specified in this file. |
| UseSearchAPI | Specifies whether the CData ADO.NET Provider for Microsoft Excel Online should use the /search(q='.xls') endpoint to locate and retrieve workbook files. When set to true (default) , the driver performs a targeted search to list only workbook files, improving efficiency in large directories. If set to false, all items are listed using the /children endpoint, and workbook files are filtered client-side. |
| UseSimpleNames | Boolean determining if simple names should be used for tables and columns. |
| ValueInputOption | Determines how the provider parses values the user submits to Microsoft Excel Online. |
| ValueRenderOption | Determines how the provider renders values in the output. |
Whether or not to treat values starting with an equals (=) sign as formulas during inserts and updates.
Set this value to true to treat values beginning with an equals (=) sign as formulas on inserts and updates. Set the value to false to treat all values used in inserts and updates as strings.
For example, with AllowFormula set to true, the following will insert a formula into the B column that will sum cells B1:B5:
INSERT INTO Excel_Sheet (A, B) VALUES ('Bill', '=SUM(B1:B5)')
Note: If True, every column containing a formula will be exposed as String type regardless of the set TypeDetectionScheme.
Indicates whether or not the provider should detect column names from the first row.
If true, the first row will be used as a column header. Otherwise, the pseudo column names A, B, C, etc. will be used.
The Sync App will follow the additional specifications below to detect column headers:
Specifies the maximum rows returned for queries without aggregation or GROUP BY.
This property sets an upper limit on the number of rows the Sync App returns for queries that do not include aggregation or GROUP BY clauses. This limit ensures that queries do not return excessively large result sets by default.
When a query includes a LIMIT clause, the value specified in the query takes precedence over the MaxRows setting. If MaxRows is set to "-1", no row limit is enforced unless a LIMIT clause is explicitly included in the query.
This property is useful for optimizing performance and preventing excessive resource consumption when executing queries that could otherwise return very large datasets.
Specifies additional hidden properties for specific use cases. These are not required for typical provider functionality. Use a semicolon-separated list to define multiple properties.
This property allows advanced users to configure hidden properties for specialized scenarios. These settings are not required for normal use cases but can address unique requirements or provide additional functionality. Multiple properties can be defined in a semicolon-separated list.
Note: It is strongly recommended to set these properties only when advised by the support team to address specific scenarios or issues.
Specify multiple properties in a semicolon-separated list.
| DefaultColumnSize | Sets the default length of string fields when the data source does not provide column length in the metadata. The default value is 2000. |
| ConvertDateTimeToGMT | Determines whether to convert date-time values to GMT, instead of the local time of the machine. |
| RecordToFile=filename | Records the underlying socket data transfer to the specified file. |
The maximum number of results to return per page from Microsoft Excel Online when UsePagination is True.
The Pagesize property affects the maximum number of results to return per page from Microsoft Excel Online. Setting a higher value may result in better performance at the cost of additional memory eaten up per page consumed. A value of -1 indicates the maximum possible page size for the driver.
Specifies the pseudocolumns to expose as table columns. Use the format 'TableName=ColumnName;TableName=ColumnName'. The default is an empty string, which disables this property.
This property allows you to define which pseudocolumns the Sync App exposes as table columns.
To specify individual pseudocolumns, use the following format: "Table1=Column1;Table1=Column2;Table2=Column3"
To include all pseudocolumns for all tables use: "*=*"
The maximum number of rows to scan to look for the columns available in a table.
The columns in a table must be determined by scanning table rows. This value determines the maximum number of rows that will be scanned.
Setting a high value may decrease performance. Setting a low value may prevent the data type from being determined properly, especially when there is null data.
Specifies the maximum time, in seconds, that the provider waits for a server response before throwing a timeout error. The default is 60 seconds. Set to 0 to disable the timeout.
This property controls the maximum time, in seconds, that the Sync App waits for an operation to complete before canceling it. If the timeout period expires before the operation finishes, the Sync App cancels the operation and throws an exception.
The timeout applies to each individual communication with the server rather than the entire query or operation. For example, a query could continue running beyond 60 seconds if each paging call completes within the timeout limit.
Setting this property to 0 disables the timeout, allowing operations to run indefinitely until they succeed or fail due to other conditions such as server-side timeouts, network interruptions, or resource limits on the server. Use this property cautiously to avoid long-running operations that could degrade performance or result in unresponsive behavior.
Determines the method for identifying the data types of columns.
The Sync App can detect data types with the cell format (number, currency, date, etc.) or by scanning rows.
| None | Setting TypeDetectionScheme to None will return all columns as the string type. |
| RowScan | Setting TypeDetectionScheme to RowScan will scan rows to heuristically determine the data type. The RowScanDepth determines the number of rows the Sync App will scan. |
| ColumnFormat | Setting TypeDetectionScheme to ColumnFormat will report the data type based on the cell format of the column.
Note: This option is applicable only for the 'UnformattedValue' ValueRenderOption. If the ValueRenderOption is set to 'FormattedValue' or 'Formula', all columns will be exposed as String types. |
Whether or not the CData ADO.NET Provider for Microsoft Excel Online should use client side paging.
Whether or not the CData Sync App should use client side paging. We suggest you set this to true in case of a large dataset.
Specifies a filepath to a JSON configuration file defining custom views. The provider automatically detects and uses the views specified in this file.
This property allows you to define and manage custom views through a JSON-formatted configuration file called UserDefinedViews.json. These views are automatically recognized by the Sync App and enable you to execute custom SQL queries as if they were standard database views. The JSON file defines each view as a root element with a child element called "query", which contains the SQL query for the view. For example:
{
"MyView": {
"query": "SELECT * FROM Test_xlsx_Sheet1 WHERE MyColumn = 'value'"
},
"MyView2": {
"query": "SELECT * FROM MyTable WHERE Id IN (1,2,3)"
}
}
You can define multiple views in a single file and specify the filepath using this property. For example: UserDefinedViews=C:\Path\To\UserDefinedViews.json. When you use this property, only the specified views are seen by the Sync App.
Refer to User Defined Views for more information.
Specifies whether the CData ADO.NET Provider for Microsoft Excel Online should use the /search(q='.xls') endpoint to locate and retrieve workbook files. When set to true (default) , the driver performs a targeted search to list only workbook files, improving efficiency in large directories. If set to false, all items are listed using the /children endpoint, and workbook files are filtered client-side.
Set this property to true to use the /search(q='.xls') endpoint for efficient workbook retrieval, particularly in large directories. If issues occur with this endpoint, set the property to false to retrieve all items and filter them client-side.
Boolean determining if simple names should be used for tables and columns.
Microsoft Excel Online tables and columns can use special characters in names that are normally not allowed in standard databases. UseSimpleNames makes the Sync App easier to use with traditional database tools.
Setting UseSimpleNames to true will simplify the names of tables and columns returned. It will enforce a naming scheme such that only alphanumeric characters and the underscore are valid for the displayed table and column names. Any nonalphanumeric characters will be converted to an underscore.
Determines how the provider parses values the user submits to Microsoft Excel Online.
Determines how the Sync App parses values the user submits to Microsoft Excel Online.
| Raw | The values the user has entered will not be parsed and will be stored as-is. |
| UserEntered | The values will be parsed as if the user typed them into the UI. Numbers will stay as numbers, but strings may be converted to numbers, dates, etc., following the same rules that are applied when entering text into a cell via the Excel Online UI. |
Determines how the provider renders values in the output.
Determines how the Sync App renders values in the output.
| FormattedValue | Values will be calculated and formatted in the reply according to the cell's formatting. Formatting is based on the workbook's locale, not the requesting user's locale. For example, if A1 is 1.23 and A2 is "=A1" and formatted as currency, then A2 would return "$1.23". |
| UnformattedValue | Values will be calculated but not formatted in the reply. For example, if A1 is 1.23 and A2 is "=A1" and formatted as currency, then A2 would return the number 1.23. |
| Formula | Values will not be calculated and instead the reply will include the formulas. For example, if A1 is 1.23 and A2 is "=A1" and formatted as currency, then A2 would return "=A1". For this reason, every column containing a formula will be exposed as String type regardless of the set TypeDetectionScheme. |
