Parse invoices & documents with Gemini AI, OCR, and Google Sheets integration
UnknownUnknown. This template uses community nodes we can't verify statically. Uses community nodes that can't be verified statically (unverified community packages are off by default in 3.0). Static check, last run 2026-10-19.
What this workflow does
This AI workflow has 10 nodes and runs when an HTTP POST request hits its webhook URL. Along the way it connects Google Sheets, Google Gemini Chat Model and Tesseractjs (community).
How it runs
Trigger: When an HTTP POST request hits its webhook URL.
- Check file type (Switch): routes items into 3 branches
- Image to Text (Tesseract Node): uses Tesseract Node
- PDF to Text (Extract from File): extracts data from a file (pdf)
- CSV to JSON (Extract from File): extracts data from a file
- Format data from text (Basic LLM Chain): sends a prompt to an LLM, with model: Google Gemini Chat Model

Services it uses
Before you upgrade to n8n 3.0
We can't fully verify this one: it relies on 1 community package, and n8n 3.0 turns unverified community packages off by default (N8N_UNVERIFIED_PACKAGES_ENABLED=false).
- Check that n8n-nodes-tesseractjs is verified or supports 3.0 (used in Image to Text).
