Use the CData ODBC Driver for Google Spanner in Microsoft Power Query

The CData ODBC Driver for Google Spanner enables you to link to Google Spanner data in Microsoft Power Query, ensuring that you see any updates. This article details how to use the ODBC driver to import Google Spanner data into Microsoft Power Query.

Connect to Google Spanner as an ODBC Data Source

If you have not already, first specify connection properties in an ODBC DSN (data source name). This is the last step of the driver installation. You can use the Microsoft ODBC Data Source Administrator to create and configure ODBC DSNs.

Google Spanner uses the OAuth authentication standard. To authenticate using OAuth, you can use the embedded credentials or register an app with Google.
