- Navigate to the Google API Console.
- Create a new project.
- Search for the Google Sheets API and enable it.
- In the left-hand navigation, go to the Credentials tab.
- Click + Create Credentials and select Service Account.
- Name the Service Account and assign it the Owner role for your project. Click Done to save.
- From the Service Accounts page, click on the Service Account you just created.
- Go to the Keys tab, then click Add Key > Create New Key.
- Choose JSON, then click Create. The JSON file will download automatically.
- Download and install the gcloud CLI.
- Run the following command to login to the gcloud CLI with the Service Account using the newly created JSON file
gcloud auth activate-service-account --key-file /path/to/key/file
- Run the following command to generate an access token:
gcloud auth print-access-token --scopes=https://www.googleapis.com/auth/spreadsheets
- Open your Google Sheet and share it with the Service Account email.
- Run DuckDB and load the extension
This token will periodically expire - you can re-run the above command again to generate a new one.

- Reading sheets where data does not start in A1 is not yet supported.
