+ AI + Duplicate Protection (n8n Workflow)\n\n⸻\n\n## Overview\n\nThis workflow automatically converts receipt images or payment proof sent via Telegram into structured financial records stored in Excel 365.\n\nCore flow:\n```\nTake Photo → OCR → AI Structuring → Validation → Duplicate Check → Append to Excel\n```\nThe system is designed to reduce manual data entry errors and improve financial visibility by turning unstructured receipt images into reliable financial records.\n\n⸻\n\n## 🧠 What This Workflow Does\n\nThis workflow automatically:\n- Captures receipt images from Telegram\n- Extracts text using OCR\n- Converts OCR text into structured transaction data using AI\n- Validates required financial fields\n- Prevents duplicate transaction entries\n- Saves valid records into Excel\n- Sends confirmation messages to Telegram\n\n⸻\n\n## 🎯 Key Benefits\n\t•\tReduce financial recording errors\n\t•\tEliminate repetitive manual data entry\n\t•\tImprove cashflow visibility\n\t•\tSimple photo-based financial recording\n\t•\tScalable foundation for AI-powered financial automation\n\n⸻\n\n## 🚀 Use Cases\n\nThis workflow is useful for:\n\t•\tSmall business owners\n\t•\tOnline sellers\n\t•\tFreelancers\n\t•\tFinance administrators\n\t•\tPersonal expense tracking\n\n⸻\n\n## 📌 Notes\n\t•\tDuplicate detection is based on a composite transaction key\n\t•\tOCR accuracy depends on image quality\n\t•\tAI parsing improves recognition compared to OCR-only approaches\n\n⸻\n\n## 🧱 Requirements\n\nTo run this workflow you need:\n\t•\tn8n (Cloud or Self-Hosted)\n\t•\tTelegram Bot Token\n\t•\tMicrosoft Excel 365 Account\n\t•\tOpenAI API Key or Google Gemini API Key\n\t•\tTesseract OCR (for self-hosted installations)\n\n⸻\n\n## 🏁 Result\n\nAfter setup, users can simply send receipt photos to Telegram and the workflow will automatically convert them into structured financial records stored in Excel.\n\nNo manual bookkeeping required.\n\n⸻\n\nBuilt for automation lovers, small businesses, and teams who want simple but powerful financial tracking using n8n."},"typeVersion":1},{"id":"f73bb7a8-7d3a-4334-8bda-b7e15d90cd40","name":"Sticky
