Invoice Parser

★ 6.5 · n8n · medium · 12 nodes

Invoice Parser is an n8n automation template that receives invoices and documents via webhook, runs OCR through Tesseract Node, extracts structured fields using Google Gemini AI, and writes the results directly into Google Sheets. Reach for it when your team is manually retyping supplier invoices into spreadsheets, when an accountant spends hours processing incoming bills, or when the volume of vendor documents has outgrown any manual workflow. Trigger: webhook. Integrations: Tesseract Node (OCR), Google Gemini (AI field extraction), Google Sheets (output). The workflow accepts a file at the webhook, OCR-converts it, lets Gemini parse amounts, dates, and counterparty details, then appends a structured row to Sheets. Deploys on any n8n instance — cloud or self-hosted — and requires Google credentials and a Gemini API key. Direction: inbound documents into a spreadsheet, not document generation or sending (use Google Docs templates for that). Works well for businesses with a steady stream of purchase invoices; not suitable when documents contain sensitive data that cannot be processed by Google cloud services.
