The workflow downloads documents, detects their type based on folder structure, and converts them to Base64 format for API processing. GPT-4o then classifies each document (invoice, receipt, contract, etc.) and extracts all relevant structured data fields with high precision.\u003c\/p\u003e\n\n\u003cp\u003eA quality assurance router evaluates extraction confidence levels automatically. High-confidence results flow directly to the \"Extractions\" tab in Google Sheets for immediate use, while low-confidence extractions are flagged in the \"Needs Review\" tab for manual verification. Complete execution logs ensure full audit trail compliance for your document processing operations.\u003c\/p\u003e\n\n\u003ch3\u003eUse cases\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eAutomated invoice processing for accounting and finance teams\u003c\/li\u003e\n\u003cli\u003eReceipt digitization for expense management systems\u003c\/li\u003e\n\u003cli\u003eContract data extraction for legal and procurement workflows\u003c\/li\u003e\n\u003cli\u003eMulti-document processing for document management systems\u003c\/li\u003e\n\u003cli\u003eFinancial document automation for bookkeeping services\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eTechnical details\u003c\/h3\u003e\n\u003cp\u003eBuilt with essential n8n nodes including Google Drive trigger and download nodes with OAuth2 authentication, dual GPT-4o nodes for document classification and data extraction, Google Sheets integration for organized output management, conditional logic nodes for quality control routing, and comprehensive error handling with execution logging.\u003c\/p\u003e\n\n\u003cp\u003eSetup requires approximately 10 minutes: connect Google Drive and Google Sheets via OAuth2, add your OpenAI API key to GPT-4o nodes, create designated Drive folders and Sheet tabs, then activate the workflow.
