Google has quietly expanded the list of tools supported for Offline Conversions Import and Customer Match, now adding Google Drive as a compatible source.
This means advertisers can now use files stored in Google Drive to import offline conversion data or upload customer lists directly via Data Manager’s direct connection workflows. Previously, data sources were limited to platforms like BigQuery, Salesforce, and Google Sheets.

By supporting Google Drive, Google is reducing friction for teams already using Drive for data handling, enabling faster, more seamless integrations with Google Ads.
You can find the full list of supported data sources in the official Data Manager documentation. Here’s a dedicated help page for Google Drive integration.
