Extract & Organize Colombian Invoices with Gmail, GPT-4o & Google Workspace

Automates extraction of Colombian invoice data from Gmail ZIP attachments using GPT-4o, validates totals, renames/uploads PDFs to Google Drive, and logs to Sheets without duplicates.

This n8n workflow streamlines personal invoice management for Colombians by monitoring Gmail for ZIP attachments containing DIAN-standard invoices. It triggers every 30 minutes, extracts PDFs and XMLs, and employs a LangChain Agent powered by GPT-4o-mini to intelligently parse critical details like document type, invoice number, dates, NITs, business names, subtotals, IVA, totals, CUFE, and a concise purchase summary. Validation ensures accuracy by checking if Total equals Subtotal + IVA. Proce
