OCR Data Extractor

OCR Data Extractor™

AI Agent for Automated Receipt Scanning, Data Extraction & Google Sheets Logging

The OCR Data Extractor is a professional AI-powered automation designed to fully automate receipt and invoice processing — from file upload to structured financial records.

Running entirely inside your n8n environment, this agent continuously monitors a Google Drive folder, extracts structured data using a powerful OCR engine, and logs clean, accurate entries into Google Sheets. It eliminates manual data entry, reduces errors, and provides real-time visibility into expenses.

Built for accuracy, scale, and operational efficiency.

How It Works

The agent watches a designated Google Drive folder for new receipts or invoices.
Once a file is detected, it is securely downloaded, processed via OCR, parsed into structured data, and appended to a Google Sheet — while automatically preventing duplicate entries.

The result: paper-based documents converted into live financial data automatically.
