Extract from uploaded files: Slack, scheduled

Runs on a schedule across Slack, PostgreSQL and Google Drive, branches on the check before anything is written, then writes the result out as a file. Built for contracts, around a "Export All Rows (PostgreSQL)" step, in 16 documented nodes.

Extract from uploaded files with Google Drive and PostgreSQL and log the results. An original, ready-to-import n8n workflow built around the 'File Processing' pattern for legal & compliance. It runs on a schedule and orchestrates 16 nodes across Slack, PostgreSQL, Google Drive. It uses n8n's LangChain AI nodes (Agent/Chain + chat model). Retry-on-fail is enabled on external calls. Import the JSON, add your credentials, and adapt the parameters. Nothing slips through the cracks.

Key benefits

  • Keeps Slack and PostgreSQL in step for contracts, without anyone re-typing a row
  • A failed Slack or PostgreSQL call is retried rather than dropped, at any of the 16 nodes in this contracts build
  • Fans the same result out to Google Drive in the same run, for contracts
  • Pinned sample data ships with it — run all 16 nodes for contracts before wiring Slack
  • 16 nodes, each with a doc card explaining what it does for contracts

Use cases

  • Teams keeping Slack and PostgreSQL aligned by hand for contracts
  • Contracts work where "Export All Rows (PostgreSQL)" is still a manual step before Slack
  • Contracts work that only reaches Slack on a schedule, 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

Advanced level

Adds branching depth and audit logging on top of the core pattern.

  • Serializing processed items back out to a file
  • Quarantining malformed rows without failing the whole batch
  • Archiving the processed file

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 (Slack, PostgreSQL, Google Drive). 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.
