AI-Driven Document Parsing and Data Extraction Workflow

This advanced n8n workflow automates the process of document ingestion, parsing, and analysis using AI-powered tools like LlamaParse and GPT models. It is designed to handle email attachments, extract structured data from diverse documents, and deliver actionable insights. The workflow starts by monitoring Gmail for incoming emails with attachments or accepts documents via webhook. It validates file formats against supported extensions, uploads files to LlamaParse for in-depth text analysis, and stores original files in Google Drive. Using sophisticated AI prompts, it classifies documents (e.g., invoices, reports), extracts key details such as dates, amounts, and transaction info, then summarizes content for quick review. Extracted data is saved into Google Sheets for record-keeping and analysis, while summaries and parsed documents are archived in Google Drive. Notifications via Telegram alert users of processing status or errors. This workflow is ideal for automated invoice processing, document management, or any scenario requiring intelligent data extraction from unstructured files combined with seamless integration across email, storage, and messaging platforms.
