Automated Invoice OCR Extraction & Structuring with AI to Sheets

Automates invoice image upload, OCR text extraction via Google Vision, AI structuring with Gemini LLM, and saves data to Google Sheets with Telegram alerts.

This n8n workflow streamlines invoice processing by enabling users to upload invoice images through a form. Files are securely stored in Google Drive, then processed with Google Vision API for accurate OCR text detection. The extracted text is fed into Gemini LLM (via OpenRouter) to intelligently parse and structure key details like date, voucher number, transaction details, vendor, and value into a consistent JSON format. A structured output parser ensures data reliability, followed by cleanin
