Receipt Extractor AI Agent
Upload a receipt image or PDF — AI extracts all structured data (date, vendor, items, amounts) and saves to Google Sheets.
The Problem
Manually entering receipt data into spreadsheets was tedious and error-prone. Staff spent hours each week typing in vendor names, amounts, dates, and line items from paper receipts and PDFs.
The Solution
Built a Receipt Extractor AI Agent powered by Google Gemini 2.0 Flash. Users upload receipt images (JPG, PNG, WEBP) or PDFs via webhook. The AI extracts date, vendor, total amount, currency, category, payment method, and individual line items with confidence scores. Data is normalized (dates to YYYY-MM-DD, amounts to numeric, currency to ISO 4217), deduplicated, and saved to Google Sheets automatically.
Built with Claude Code
Gemini multimodal extraction prompt + ISO normalization rules engineered with Claude Code. Confidence-score schema validated by n8n-validation-expert.
