Connect your Google Sheet

Read-only, straight from your browser. Nothing is sent anywhere else.

The long ID in your sheet URL: docs.google.com/spreadsheets/d/<THIS PART>/edit
Stored only in this browser (localStorage). Restrict the key to the Sheets API.
One-time Google setup
  1. Go to console.cloud.google.com → create/select a project.
  2. APIs & Services → Library → enable Google Sheets API.
  3. APIs & Services → Credentials → Create credentials → API key. Restrict it to the Sheets API.
  4. In your spreadsheet: Share → General access → Anyone with the link: Viewer. (API-key access only works on link-viewable sheets — an unavoidable Google rule. Use OAuth later if the data must stay fully private.)
