Create a connection to Excel Services by navigating to the Connections page in the Sync App application and selecting the corresponding icon in the Add Connections panel. If the Excel Services icon is not available, click the Add More icon to download and install the Excel Services connector from the CData site.

Required properties are listed under the Settings tab. The Advanced tab lists connection properties that are not typically required.

This section provides the details for connecting SharePoint On Premises.

Connecting to a Workbook

Regardless of which edition of SharePoint you are using, set File to the Excel workbook. This path is relative to the following properties:

• Library: The Shared Documents library is used by default. You can use this property to specify another document library in your organization; for example, if you want to connect to OneDrive for Business, set this property to "Documents".
• Folder: You can use this property to specify a path to a subfolder in a library. The path is relative to the library name specified in Library.

Connecting to Spreadsheet Data as Tables

The Sync App detects the available tables based on the available objects in the underlying API.

The APIs surface different API objects; select the API based on the organization of your spreadsheets and your SharePoint version:

• OData: The OData API allows access to tables defined from Excel table objects (not ranges or spreadsheets), which you create by clicking Insert > Table in Excel. When connecting to the OData API, the Sync App may not return any tables if you do not have table objects defined in your workbook. Set UseRESTAPI to true to connect to spreadsheets or ranges as tables.
• REST: The REST API enables access to tables defined from Excel table objects, ranges, and spreadsheets. This is the default API. Requesting a large number of rows from ranges and spreadsheets is restricted by the REST API, and the Sync App limits the number of rows returned to 100 by default. The Sync App also defaults to detecting column names from the first row; set Header to disable this.

With DefineTables additionally set, you can define tables based on ranges, using the Excel range syntax. A range that is too large will be restricted by the API.

See Data Model for more information on how the Sync App detects tables and how to query them.

Connecting to SharePoint On Premises

Set the Url to your server's name or IP address. Additionally, set SharePointVersion and the authentication values.

To authenticate to SharePoint OnPremise, set AuthScheme to the authentication type and set User and Password, if necessary.

Note: When connecting to SharePoint On-Premises 2010, you must set UseRESTAPI to true.

• Windows (NTLM)

  This is the most common authentication type. As such, the Sync App is preconfigured to use NTLM as the default; simply set the Windows User and Password to connect.

• Kerberos

  Please see Using Kerberos for details on how to authenticate with Kerberos.

• Forms

  This allows authentication through a custom authentication method, instead of Active Directory. To use this authentication type, set AuthScheme to FORMS and set the User and Password.

• ADFS

  Set the AuthScheme to ADFS. The following connection properties need to be set:

  • User: Set this to the ADFS user.
  • Password: Set this to ADFS password for the user.
  • SSOLoginURL: Set this to the WS-trust endpoint of the ADFS server.
  The following SSOProperties are needed to authenticate to ADFS:
  • RelyingParty: The value of the relying party identifier on the ADFS server for Sharepoint.
  Below is an example connection string:
  

  AuthScheme=ADFS;User=ADFSUserName;Password=ADFSPassword;SSOLoginURL=https://<authority>/adfs/services/trust/2005/usernamemixed;SSO Properties ='RelyingParty=urn:sharepoint:sp2016;';

• Anonymous Access

  Set the AuthScheme to NONE along with the URL.

Fine Tuning Data Access

To make it easier to access data in advanced integrations, you can use the following:

• TypeDetectionScheme: You can use this property to enable or disable automatic type detection based on the value specified in RowScanDepth.
• RowScanDepth: This property determines the number of rows that will be scanned to determine column data types.

Troubleshooting

413 Request Entity Too Large

This error occurs when a workbook has too much data per row. Generally, solution to this error will be to make the Excel table smaller or to make the rows less dense.

However, setting the following connection properties will enable you to work around this limitation. Note: This workaround is only supported when using the REST API.

• DefineTables: Set this to the desired cell range in your sheet.
• Other: Set this to PageSize=X to determine the number of records that will be paged through at once. Each page should contain less than 100kb. Note that smaller page sizes also entail slower perfomance.

This section shows how to use the Sync App to authenticate using Kerberos.

Kerberos

To authenticate to Excel Services using Kerberos, set the following properties:

• AuthScheme: Set this to NEGOTIATE.
• KerberosKDC: Set this to the host name or IP Address of your Kerberos KDC machine.
• KerberosSPN: Set this to the service and host of the Excel Services Kerberos Principal. This is the value prior to the '@' symbol (for instance, ServiceName/MyHost) of the principal value (for instance, ServiceName/[email protected]).

Retrieve the Kerberos Ticket

You can use one of the following options to retrieve the required Kerberos ticket.

MIT Kerberos Credential Cache File

This option enables you to use the MIT Kerberos Ticket Manager or kinit command to get tickets. Note that you do not need to set the User or Password connection properties with this option.

1. Ensure that you have an environment variable created called KRB5CCNAME.
2. Set the KRB5CCNAME environment variable to a path pointing to your credential cache file (for instance, C:\krb_cache\krb5cc_0 or /tmp/krb5cc_0). This file is created when generating your ticket with MIT Kerberos Ticket Manager.
3. To obtain a ticket, open the MIT Kerberos Ticket Manager application, click Get Ticket, enter your principal name and password, then click OK. If successful, ticket information appears in Kerberos Ticket Manager and is stored in the credential cache file.
4. Now that you have created the credential cache file, the Sync App uses the cache file to obtain the Kerberos ticket to connect to Excel Services.

As an alternative to setting the KRB5CCNAME environment variable, you can directly set the file path using the KerberosTicketCache property. When set, the Sync App uses the specified cache file to obtain the Kerberos ticket to connect to Excel Services.

Keytab File

If the KRB5CCNAME environment variable has not been set, you can retrieve a Kerberos ticket using a Keytab File. To do so, set the User property to the desired username and set the KerberosKeytabFile property to a file path pointing to the keytab file associated with the user.

User and Password

If both the KRB5CCNAME environment variable and the KerberosKeytabFile property have not been set, you can retrieve a ticket using a user and password combination. To do this, set the User and Password properties to the user/password combination that you use to authenticate with Excel Services.

Cross-Realm

More complex Kerberos environments may require cross-realm authentication where multiple realms and KDC servers are used (e.g., where one realm/KDC is used for user authentication and another realm/KDC is used for obtaining the service ticket).

In such an environment, set the KerberosRealm and KerberosKDC properties to the values required for user authentication. Also set the KerberosServiceRealm and KerberosServiceKDC properties to the values required to obtain the service ticket.

This section details a selection of advanced features of the Excel Services Sync App.

User Defined Views

The Sync App allows you to define virtual tables, called user defined views, whose contents are decided by a pre-configured query. These views are useful when you cannot directly control queries being issued to the drivers. See User Defined Views for an overview of creating and configuring custom views.

SSL Configuration

Use SSL Configuration to adjust how Sync App handles TLS/SSL certificate negotiations. You can choose from various certificate formats; see the SSLServerCert property under "Connection String Options" for more information.

Firewall and Proxy

Configure the Sync App for compliance with Firewall and Proxy, including Windows proxies and HTTP proxies. You can also set up tunnel connections.

Query Processing

The Sync App offloads as much of the SELECT statement processing as possible to Excel Services and then processes the rest of the query in memory (client-side).

See Query Processing for more information.

Logging

See Logging for an overview of configuration settings that can be used to refine CData logging. For basic logging, you only need to set two connection properties, but there are numerous features that support more refined logging, where you can select subsets of information to be logged using the LogModules connection property.

Customizing the SSL Configuration

By default, the Sync App attempts to negotiate SSL/TLS by checking the server's certificate against the system's trusted certificate store.

To specify another certificate, see the SSLServerCert property for the available formats to do so.

Connecting Through a Firewall or Proxy

HTTP Proxies

To connect through the Windows system proxy, you do not need to set any additional connection properties. To connect to other proxies, set ProxyAutoDetect to false.

In addition, to authenticate to an HTTP proxy, set ProxyAuthScheme, ProxyUser, and ProxyPassword, in addition to ProxyServer and ProxyPort.

Other Proxies

Set the following properties:

• To use a proxy-based firewall, set FirewallType, FirewallServer, and FirewallPort.
• To tunnel the connection, set FirewallType to TUNNEL.
• To authenticate, specify FirewallUser and FirewallPassword.
• To authenticate to a SOCKS proxy, additionally set FirewallType to SOCKS5.

The Sync App supports retrieving Excel data from SharePoint On-Premises through the REST API and through the OData API introduced in SharePoint 2013. Excel files must have the .xlsx format used in Excel 2007 and later.

Note: Microsoft has stated that they plan to sunset the Excel Services API for SharePoint Online in February 2022. Please consider migrating to the CData Sync App for Excel Online for future access to your SharePoint data.

The Sync App can detect the tables in your workbook based on the following:

• Spreadsheets
• Excel tables
• Ranges

Dynamic Metadata Querying

Through dynamic metadata querying, any changes you make in Excel, such as adding an Excel table or spreadsheet or modifying columns, are reflected when you reconnect.

Configuring Table Detection

The OData API and REST API (the default) each surface different API objects. Select which API to use based on how your workbook is organized and your Excel Services version.

Connecting to Excel Tables

The OData API surfaces only the Excel tables you defined in your spreadsheets with Insert -> Table.

Connecting to Spreadsheets, Ranges, and Excel Tables

If you need to access data outside of Excel tables, set UseRESTAPI to true; the REST API enables access to spreadsheets, ranges, and Excel tables as database tables.

See REST API for more information on executing SQL to spreadsheets and ranges.

Supported APIs by SharePoint Version

The following table shows which APIs are available for each SharePoint version:

When using the OData protocol, you can access only data defined within Excel tables in the spreadsheet, which you create by clicking Insert -> Table in Excel.

Therefore if you have data outside a table object, this data cannot be retrieved using the OData API. Thus you may see a case where no tables are returned. This is a function of the OData API and you may want to look at using the REST API in such a case.

When you are using the REST API, you can select data from the following tables:

• Spreadsheets in the workbook
• Excel table objects
• Ranges you specify in DefineTables

Resolving Name Collisions

When one or more tables have the same name, the Sync App uses the following precedence in decreasing order to resolve the collision: ranges -> Excel tables -> sheets.

For example: MyTable is in DefineTables and there is also an Excel table with the same name in the workbook. The definition specified within DefineTables overrides the Excel table.

Selecting from Spreadsheets

To select data from a spreadsheet, specify the spreadsheet name in the FROM clause. By default, the first row is used to determine column names. You can set Header to false to disable automatic column name detection.

The data range is A1:Z100. To specify a different range, use DefineTables.

Selecting from Excel Tables

To select data from an Excel table object, specify the table name in the FROM clause. These are the tables you create by clicking Insert -> Table in Excel.

Selecting from Ranges

You can use the standard Excel format to define ranges; map the range to a table name in DefineTables.

Data Type Mappings

The Sync App maps types from the data source to the corresponding data type available in the schema. The table below documents these mappings.

This section provides a complete list of the Connection properties you can configure in the connection string for this provider.

Define the tables within a spreadsheet.

Remarks

This property is used to define the ranges within a spreadsheet that will appear as tables, when using the REST API. The value is a comma-separated list of name-value pairs in the form [Table Name]=[Sheet Name]![Range]. Table Name is the name of the table you want to use for the data and will be used when issuing queries. Sheet Name is the name of the sheet within the spreadsheet and Range is the range of cells that contain the data for the table.

Here is an example DefineTables value: DefineTables="DefinedTable1=Sheet1!A1:N25,DefinedTable2=Sheet2!C3:M53"

Note: If the name of a defined table is the same as one returned by default (e.g. same name as a worksheet), the defined table will replace the default table.

The name of the Excel file to which to connect.

Remarks

The name of Excel file to which to connect (including the extension ".xlsx"). The file must exist.

The folder containing the workbook specified by the File property.

Remarks

The full, hierarchical path of the subfolder in a Library where the File can be found. For example if the File is located in a folder called "SubFolder" within the folder called "BaseFolder", the property will be set to "/BaseFolder/SubFolder/".

Indicates whether the first row should be used as a column header when using the REST API.

Remarks

If true, the first row will be used as a column header. Otherwise, the pseudo column names A, B, C, etc. will be used.

Note: This property is only used when UseRESTAPI is 'True'.

This section provides a complete list of the Kerberos properties you can configure in the connection string for this provider.

The Kerberos Key Distribution Center (KDC) service used to authenticate the user.

Remarks

The Kerberos properties are used when using SPNEGO or Windows Authentication. The Sync App will request session tickets and temporary session keys from the Kerberos KDC service. The Kerberos KDC service is conventionally colocated with the domain controller.

If Kerberos KDC is not specified, the Sync App will attempt to detect these properties automatically from the following locations:

• KRB5 Config File (krb5.ini/krb5.conf): If the KRB5_CONFIG environment variable is set and the file exists, the Sync App will obtain the KDC from the specified file. Otherwise, it will attempt to read from the default MIT location based on the OS: C:\ProgramData\MIT\Kerberos5\krb5.ini (Windows) or /etc/krb5.conf (Linux).
• Domain Name and Host: If the Kerberos Realm and Kerberos KDC could not be inferred from another location, the Sync App will infer them from the configured domain name and host.

The Kerberos Realm used to authenticate the user.

Remarks

The Kerberos properties are used when using SPNEGO or Windows Authentication. The Kerberos Realm is used to authenticate the user with the Kerberos Key Distribution Service (KDC). The Kerberos Realm can be configured by an administrator to be any string, but conventionally it is based on the domain name.

If Kerberos Realm is not specified, the Sync App will attempt to detect these properties automatically from the following locations:

• KRB5 Config File (krb5.ini/krb5.conf): If the KRB5_CONFIG environment variable is set and the file exists, the Sync App will obtain the default realm from the specified file. Otherwise, it will attempt to read from the default MIT location based on the OS: C:\ProgramData\MIT\Kerberos5\krb5.ini (Windows) or /etc/krb5.conf (Linux)
• Domain Name and Host: If the Kerberos Realm and Kerberos KDC could not be inferred from another location, the Sync App will infer them from the user-configured domain name and host. This might work in some Windows environments.

The service principal name (SPN) for the Kerberos Domain Controller.

Remarks

If the SPN on the Kerberos Domain Controller is not the same as the URL that you are authenticating to, use this property to set the SPN.

The Keytab file containing your pairs of Kerberos principals and encrypted keys.

Remarks

The Keytab file containing your pairs of Kerberos principals and encrypted keys.

The Kerberos realm of the service.

Remarks

The KerberosServiceRealm is the specify the service Kerberos realm when using cross-realm Kerberos authentication.

This property is available for complex setups where a different realm and KDC machine are used to obtain an authentication ticket (AS request) and a service ticket (TGS request).

The Kerberos KDC of the service.

Remarks

The KerberosServiceKDC is used to specify the service Kerberos KDC when using cross-realm Kerberos authentication.

In most cases, a single realm and KDC machine are used to perform the Kerberos authentication and this property is not required.

This property is available for complex setups where a different realm and KDC machine are used to obtain an authentication ticket (AS request) and a service ticket (TGS request).

The full file path to an MIT Kerberos credential cache file.

Remarks

This property can be set if you wish to use a credential cache file that was created using the MIT Kerberos Ticket Manager or kinit command.

This section provides a complete list of the SSL properties you can configure in the connection string for this provider.

The certificate to be accepted from the server when connecting using TLS/SSL.

Remarks

If using a TLS/SSL connection, this property can be used to specify the TLS/SSL certificate to be accepted from the server. Any other certificate that is not trusted by the machine is rejected.

This property can take the following forms:

If not specified, any certificate trusted by the machine is accepted.

Use '*' to signify to accept all certificates. Note that this is not recommended due to security concerns.

This section provides a complete list of the Firewall properties you can configure in the connection string for this provider.

The protocol used by a proxy-based firewall.

Remarks

This property specifies the protocol that the Sync App will use to tunnel traffic through the FirewallServer proxy. Note that 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.

To connect to HTTP proxies, use ProxyServer and ProxyPort. To authenticate to HTTP proxies, use ProxyAuthScheme, ProxyUser, and ProxyPassword.

The name or IP address of a proxy-based firewall.

Remarks

This property specifies the IP address, DNS name, or host name of a proxy allowing traversal of a firewall. The protocol is specified by FirewallType: Use FirewallServer with this property to connect through SOCKS or do tunneling. Use ProxyServer to connect to an HTTP proxy.

Note that the Sync App uses the system proxy by default. To use a different proxy, set ProxyAutoDetect to false.

This section provides a complete list of the Proxy properties you can configure in the connection string for this provider.

This indicates whether to use the system proxy settings or not. This takes precedence over other proxy settings, so you'll need to set ProxyAutoDetect to FALSE in order use custom proxy settings.

Remarks

This takes precedence over other proxy settings, so you'll need to set ProxyAutoDetect to FALSE in order use custom proxy settings.

To connect to an HTTP proxy, see ProxyServer. For other proxies, such as SOCKS or tunneling, see FirewallType.

The hostname or IP address of a proxy to route HTTP traffic through.

Remarks

The hostname or IP address of a proxy to route HTTP traffic through. The Sync App can use the HTTP, Windows (NTLM), or Kerberos authentication types to authenticate to an HTTP proxy.

If you need to connect through a SOCKS proxy or tunnel the connection, see FirewallType.

By default, the Sync App uses the system proxy. If you need to use another proxy, set ProxyAutoDetect to false.

The TCP port the ProxyServer proxy is running on.

Remarks

The port the HTTP proxy is running on that you want to redirect HTTP traffic through. Specify the HTTP proxy in ProxyServer. For other proxy types, see FirewallType.

The authentication type to use to authenticate to the ProxyServer proxy.

Remarks

This value specifies the authentication type to use to authenticate to the HTTP proxy specified by ProxyServer and ProxyPort.

Note that the Sync App will use the system proxy settings by default, without further configuration needed; if you want to connect to another proxy, you will need to set ProxyAutoDetect to false, in addition to ProxyServer and ProxyPort. To authenticate, set ProxyAuthScheme and set ProxyUser and ProxyPassword, if needed.

The authentication type can be one of the following:

• BASIC: The Sync App performs HTTP BASIC authentication.
• DIGEST: The Sync App performs HTTP DIGEST authentication.
• NEGOTIATE: The Sync App retrieves an NTLM or Kerberos token based on the applicable protocol for authentication.
• PROPRIETARY: The Sync App does not generate an NTLM or Kerberos token. You must supply this token in the Authorization header of the HTTP request.

If you need to use another authentication type, such as SOCKS 5 authentication, see FirewallType.

A user name to be used to authenticate to the ProxyServer proxy.

Remarks

The ProxyUser and ProxyPassword options are used to connect and authenticate against the HTTP proxy specified in ProxyServer.

You can select one of the available authentication types in ProxyAuthScheme. If you are using HTTP authentication, set this to the user name of a user recognized by the HTTP proxy. If you are using Windows or Kerberos authentication, set this property to a user name in one of the following formats:

user@domain
domain\user

Remarks

This property determines when to use SSL for the connection to an HTTP proxy specified by ProxyServer. This value can be AUTO, ALWAYS, NEVER, or TUNNEL. The applicable values are the following:

A semicolon separated list of destination hostnames or IPs that are exempt from connecting through the ProxyServer .

Remarks

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, you need to set ProxyAutoDetect = false, and configure ProxyServer and ProxyPort. To authenticate, set ProxyAuthScheme and set ProxyUser and ProxyPassword, if needed.

This section provides a complete list of the Logging properties you can configure in the connection string for this provider.

Core modules to be included in the log file.

Remarks

Only the modules specified (separated by ';') will be included in the log file. By default all modules are included.

See the Logging page for an overview.

This section provides a complete list of the Schema properties you can configure in the connection string for this provider.

A path to the directory that contains the schema files defining tables, views, and stored procedures.

Remarks

The path to a directory which contains the schema files for the Sync App (.rsd files for tables and views, .rsb files for stored procedures). The folder location can be a relative path from the location of the executable. The Location property is only needed if you want to customize definitions (for example, change a column name, ignore a column, and so on) or extend the data model with new tables, views, or stored procedures.

If left unspecified, the default location is "%APPDATA%\\CData\\Microsoft SharePoint Excel Data Provider\\Schema" with %APPDATA% being set to the user's configuration directory:

This property restricts the schemas reported to a subset of the available schemas. For example, BrowsableSchemas=SchemaA,SchemaB,SchemaC.

Remarks

Listing the schemas from databases can be expensive. Providing a list of schemas in the connection string improves the performance.

This property restricts the tables reported to a subset of the available tables. For example, Tables=TableA,TableB,TableC.

Remarks

Listing the tables from some databases can be expensive. Providing a list of tables in the connection string improves the performance of the Sync App.

This property can also be used as an alternative to automatically listing views if you already know which ones you want to work with and there would otherwise be too many to work with.

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 that when connecting to a data source with multiple schemas or catalogs, you will need to provide the fully qualified name of the table in this property, as in the last example here, to avoid ambiguity between tables that exist in multiple catalogs or schemas.

Restricts the views reported to a subset of the available tables. For example, Views=ViewA,ViewB,ViewC.

Remarks

Listing the views from some databases can be expensive. Providing a list of views in the connection string improves the performance of the Sync App.

This property can also be used as an alternative to automatically listing views if you already know which ones you want to work with and there would otherwise be too many to work with.

Specify the views you want in a comma-separated list. Each view should be a valid SQL identifier with any special characters escaped using square brackets, double-quotes or backticks. For example, Views=ViewA,[ViewB/WithSlash],WithCatalog.WithSchema.`ViewC With Space`.

Note that when connecting to a data source with multiple schemas or catalogs, you will need to provide the fully qualified name of the table in this property, as in the last example here, to avoid ambiguity between tables that 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.

Indicates if navigation parent columns should be included on navigation views.

Remarks

When NavigationPropertiesAsViews is set to true, this property controls if parent columns from the navigation property will be displayed or not on the view. It may be worth displaying them in order to take advantage of being able to filter based on information about the parent.

When set to false, the primary keys of the parent will still be displayed to allow for joining back to the parent, but other other columns will not be.

These hidden properties are used only in specific use cases.

Remarks

The properties listed below are available for specific use cases. Normal driver use cases and functionality should not require these properties.

Specify multiple properties in a semicolon-separated list.

Integration and Formatting

This property indicates whether or not to include pseudo columns as columns to the table.

Remarks

This setting is particularly helpful in Entity Framework, which does not allow you to set a value for a pseudo column unless it is a table column. The value of this connection setting is of the format "Table1=Column1, Table1=Column2, Table2=Column3". You can use the "*" character to include all tables and all columns; for example, "*=*".

The maximum number of rows to scan to look for the columns available in a table.

Remarks

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.

Indicates whether or not the empty rows should be pushed when UseRESTAPI = true.

A filepath pointing to the JSON configuration file containing your custom views.

Remarks

User Defined Views are defined in a JSON-formatted configuration file called UserDefinedViews.json. The Sync App automatically detects the views specified in this file.

You can also have multiple view definitions and control them using the UserDefinedViews connection property. When you use this property, only the specified views are seen by the Sync App.

This User Defined View configuration file is formatted as follows:

• Each root element defines the name of a view.
• Each root element contains a child element, called query, which contains the custom SQL query for the view.

For example:

{
	"MyView": {
		"query": "SELECT * FROM Account WHERE MyColumn = 'value'"
	},
	"MyView2": {
		"query": "SELECT * FROM MyTable WHERE Id IN (1,2,3)"
	}
}
