n8n LlamaParse AI Document Parsing & Data Extraction

n8n LlamaParse AI Document Parsing lets you automate document processing, text extraction, document classification, summarization, and invoice data extraction with n8n, LlamaParse, and OpenAI.

In this workflow, Gmail is monitored for emails containing attachments. The workflow retrieves the attachment, checks its file extension against the formats supported by LlamaParse, and sends supported documents to LlamaParse for parsing.

The original document is saved to Google Drive, while LlamaParse processes the document and returns parsed Markdown to n8n through a webhook.

From there, OpenAI analyzes the parsed content and classifies the document into different processing paths.

📄 GENERAL DOCUMENT PROCESSING

For general documents, the workflow uses AI to create a detailed summary covering important information such as:

• Executive summary
• Key themes and main points
• Notable findings
• Important data and statistics
• Recommendations and action items
• Further areas for investigation
• Potential implications

The resulting summary can be sent to Telegram and saved as a Markdown document in Google Drive.

🧾 AI INVOICE DATA EXTRACTION

When the document is identified as an invoice, the workflow uses AI to extract structured invoice information as JSON.

The invoice extraction schema includes information such as:

• Statement date
• Organization or member
• Transactions
• Payment details
• Subtotal
• Fees and tips
• GST and PST
• Liquor PST
• Deposits
• Savings
• Final amount
• Payment terms
• Additional information
• Invoice summary

The extracted invoice information is then sent through Telegram and selected structured information is updated in Google Sheets.

📊 DOCUMENT STORAGE & DATA TRACKING

Google Drive is used to store the original document, parsed Markdown, and generated summaries.

Google Sheets is used to save processing information and structured invoice data, making the extracted information easier to track and analyze.

📱 TELEGRAM NOTIFICATIONS

Telegram is used to deliver document summaries, invoice information, and error notifications for convenient review.
