  • What you will learn
  • Watch the episode

In a previous episode we built a workflow that extracted data from a single receipt. In this video I extend it so that one run processes multiple documents at once — several photos of receipts or invoices uploaded together.

What you will learn

  • How to modify the AI agent prompt so it returns an array of objects instead of a single object.
  • How to handle the array in the agent output and split it into separate workflow items.
  • How to automatically write multiple rows to Google Sheets in a single run.
  • What to watch out for when running OCR on documents with different layouts.

This builds directly on the episode about automating receipt OCR — start there if you have not seen it yet.

Watch the episode

The video is available on YouTube: youtube.com/watch?v=PPej1Vn-w0U.

All episodes are collected on the Automation Academy page (in Polish). Subscribe to my YouTube channel so you do not miss new material.

The video is in Polish; this post summarizes what it covers.
