Invoice Processor & Validator with OCR, AI & Google Sheets

This workflow revolutionizes invoice handling by automating the entire pipeline from PDF input to validated data in Google Sheets. It starts by reading a local PDF invoice, applies OCR to extract raw text from scanned or digital documents, and uses an AI agent to intelligently parse and convert messy text into clean, structured JSON. Further nodes refine this JSON, split out individual line items with details, generate unique keys for tracking, and seamlessly update a designated Google Sheet.

Validation is a key strength: it fetches master item data from your records, compares extracted item names and costs for accuracy, and marks each as 'Valid' or 'Invalid' directly in the sheet. This eliminates manual checks, detects billing errors early, and ensures compliance without effort.

Ideal for businesses, freelancers, and ops teams dealing with frequent invoices, it saves hours of tedious work, boosts accuracy with AI-powered intelligence, and integrates effortlessly with Google Sheets for logging and reporting. Fast, scalable, and zero manual intervention required.
