To connect to Excel Services, you can use either a DSN or an ODBC connection string. Both of these methods use the odbc_connect function.

Connect to a DSN

To connect using a DSN:

$cnx = odbc_connect("CData ExcelServices Sys", "", "");

Provide a Driver Connection String

To connect using an ODBC connection string:

$cnx = odbc_connect("DRIVER={CData ODBC Driver for Microsoft SharePoint Excel};Url=https://myorg.sharepoint.com;[email protected];Password=password;File=Book1.xlsx;", "", "");
