Create contracts for ocr & extraction

Fires the moment a webhook arrives across Google Sheets, Slack and Airtable, parses the incoming file into rows, then branches on the check before anything is written. Built for ocr & extraction, around a "Download Source File" step, in 21 documented nodes.

Create contracts with HTTP / REST API and Airtable on autopilot. An original, ready-to-import n8n workflow built around the 'Document Generation' pattern for legal & compliance. It fires on a webhook and orchestrates 21 nodes across Google Sheets, Slack, HTTP / REST API. Retry-on-fail is enabled on external calls. Import the JSON, add your credentials, and adapt the parameters. What used to take a morning now runs on its own.

Key benefits

  • ✓Keeps Google Sheets and Slack in step for ocr & extraction, without anyone re-typing a row
  • ✓Safe to re-run: records already in Google Sheets or Slack are skipped, across all 21 nodes of this ocr-&-extraction build
  • ✓A failed Google Sheets or Slack call is retried rather than dropped, at any of the 21 nodes in this ocr-&-extraction build
  • ✓Every ocr-&-extraction run leaves an audit row behind, alongside Google Sheets
  • ✓Fans the same result out to Airtable in the same run, for ocr & extraction

Use cases

  • →Teams keeping Google Sheets and Slack aligned by hand for ocr & extraction
  • →Pushing ocr-&-extraction events into Google Sheets and Slack the moment they land, not on the next poll
  • →Ocr & extraction work where "Download Source File" is still a manual step before Google Sheets
  • →Ocr & extraction work that only reaches Google Sheets when a webhook arrives, when someone remembers to start it

From download to running in 3 steps

  1. 1
    Import. In n8n, open Workflows → menu → “Import from File” and pick the downloaded JSON.
  2. 2
    Connect. Add your own credentials on the app nodes - n8n highlights exactly which ones need them.
  3. 3
    Activate. Run it once to test, then toggle Active. The automation is live.

What you'll learn

Production level

Production-grade: idempotency, dead-letter handling, and reconciliation included.

  • •Pulling text out of an uploaded file before parsing it
  • •Validating required fields before the write
  • •Upserting so reprocessing a document does not duplicate it

Every node carries its own documentation on the canvas, plus notes explaining why the architecture was built this way, a credential setup guide, troubleshooting, and three practice exercises. Sample data comes pinned to the trigger, so you can hit Execute and watch data flow before connecting a single account.

Common questions

What exactly do I get?

The complete, ready-to-import n8n workflow as a JSON file, delivered instantly after payment. Import it into your own n8n (cloud or self-hosted), add your credentials, and it runs.

How do I import it into n8n?

In n8n, open Workflows, click the three-dot menu, choose “Import from File”, and select the downloaded JSON. Then connect your own app credentials on the highlighted nodes.

Do I need anything else for it to work?

You need your own n8n instance and accounts/credentials for the apps this workflow connects to (Google Sheets, Slack, HTTP / REST API, Airtable). No coding is required.

What if it doesn't work for me?

If the file is faulty, won't import, or isn't as described, contact us within 7 days and we'll fix it or refund you - see our refund policy.

Can I modify or resell it?

You can freely adapt and use it in your own or your clients' projects. Reselling or redistributing the template file itself is not permitted.
