N8n workflow: Google Sheets → Slack notifications when new rows are added in google sheets

Hey everyone!

Built a workflow that monitors any Google Sheet and sends
instant Slack notifications whenever a new row is added.

Features:

  • No duplicate notifications (fingerprint-based detection)
  • First-run safe — won’t spam your existing rows
  • Rate limiting to avoid Slack API issues
  • Retries automatically if Slack is temporarily unavailable
  • Works with any sheet structure

Use cases: sales leads, form submissions, order tracking,
inventory updates — anything you track in Google Sheets.

Setup takes about 3 minutes:

  1. Import the JSON
  2. Add your Spreadsheet ID
  3. Connect Google Sheets + Slack credentials
  4. Publish
