The easiest way to connect to a Google Sheet using Airbyte is through Airbyte Cloud with OAuth authentication. Here's a brief overview of the process: 1. Log into your Airbyte Cloud account. 2. Go to the Sources page and select "Google Sheets" as your source. 3. Choose "Authenticate via Google (OAuth)" from the Authentication dropdown. 4. Click "Sign in with Google" and complete the authentication workflow. 5. Enter the link to your Google Sheet in the "Spreadsheet Link" field. This method is recommended as it significantly simplifies the setup process by allowing you to authenticate directly from the Airbyte UI. For more detailed instructions, you can refer to the [Google Sheets Source Setup Guide](

If you're using Airbyte Open Source, the process is slightly different and may require additional steps, such as setting up a service account or using OAuth with manual credential input.
