Automate Document Parsing to Google Sheets with AI and OCR

This n8n workflow automates the parsing of documents such as invoices, logs, and sensor reports from PDFs, images, and CSVs. It extracts key fields using OCR and AI, then stores the structured data in Google Sheets.

The workflow begins with a webhook trigger that receives document uploads. It then uses a switch node to determine the file type: images are processed with Tesseract OCR, PDFs with a PDF parser, and CSVs are extracted directly. The extracted text is analyzed by Google Gemini AI to identify fields like invoice ID, total, and customer name. The resulting JSON data is cleaned and appended to a Google Sheet, facilitating automated data entry and reducing manual processing time.
