MuleSoft Connector for Excel Services

Build 20.0.7587

Advanced Settings

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.

Customizing the SSL Configuration

By default, the connector 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.

Troubleshooting the Connection

To show connector activity from query execution to network traffic, use Logfile and Verbosity. The examples of common connection errors below show how to use these properties to get more context. Contact the support team for help tracing the source of an error or circumventing a performance issue.

  • Authentication errors: Typically, recording a Logfile at Verbosity 4 is necessary to get full details on an authentication error.
  • Queries time out: A server that takes too long to respond will exceed the connector's client-side timeout. Often, setting the Timeout property to a higher value will avoid a connection error. Another option is to disable the timeout by setting the property to 0. Setting Verbosity to 2 will show where the time is being spent.
  • The certificate presented by the server cannot be validated: This error indicates that the connector cannot validate the server's certificate through the chain of trust. If you are using a self-signed certificate, there is only one certificate in the chain.

    To resolve this error, you must verify yourself that the certificate can be trusted and specify to the connector that you trust the certificate. One way you can specify that you trust a certificate is to add the certificate to the trusted system store; another is to set SSLServerCert.

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.
