Extract from receipts: Slack + sub-workflow
Runs on a schedule across Slack, Google Sheets and Google Drive, branches on the check before anything is written, then drops anything it has already handled. Built for ocr & extraction, around a "Export All Rows (Google Sheets)" step, in 31 documented nodes.
Extract from receipts with Google Drive and MySQL automatically. An original, ready-to-import n8n workflow built around the 'File Processing' pattern for legal & compliance. It runs on a schedule and orchestrates 31 nodes across Slack, Google Sheets, 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. What used to take a morning now runs on its own.
Key benefits
- ✓Keeps Slack and Google Sheets in step for ocr & extraction, without anyone re-typing a row
- ✓Safe to re-run: records already in Slack or Google Sheets are skipped, across all 31 nodes of this ocr-&-extraction build
- ✓A failed Slack or Google Sheets call is retried rather than dropped, at any of the 31 nodes in this ocr-&-extraction build
- ✓Every ocr-&-extraction run leaves an audit row behind, alongside Slack
- ✓Fans the same result out to Google Drive in the same run, for ocr & extraction
Use cases
- →Teams keeping Slack and Google Sheets aligned by hand for ocr & extraction
- →Ocr & extraction work where "Export All Rows (Google Sheets)" is still a manual step before Slack
- →Ocr & extraction work that only reaches Slack on a schedule, when someone remembers to start it

What's inside (31 nodes)
A look at the node types this workflow uses. No purchase required — full parameters and credentials are yours after you buy.
From download to running in 3 steps
- 1Import. In n8n, open Workflows → menu → “Import from File” and pick the downloaded JSON.
- 2Connect. Add your own credentials on the app nodes - n8n highlights exactly which ones need them.
- 3Activate. Run it once to test, then toggle Active. The automation is live.
What you'll learn
Architect levelThe deepest tier - sub-workflow delegation, state snapshots, and full observability.
- •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, Google Sheets, Google Drive, HTTP / REST API, …). 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.
