Generate technical n8n workflow reports with GPT-4.1 and Google Docs

Who is this workflow for?

This workflow is designed for technical teams, automation owners, process auditors, and anyone who needs to document n8n workflows in a consistent, fast, and professional way—without manual work.

What problem does it solve? / Use case

Documenting n8n workflows is often slow and error-prone: you need to review nodes, configurations, connections, internal logic, and embedded code.

This workflow automates that process by generating a complete technical report, structured and ready to share, ensuring documentation is:

- consistent - easy to update - easy to review - accessible in Google Drive

What this workflow does

- Lets you select an n8n workflow to document - Extracts its structure, nodes, connections, and settings - Normalizes the JSON to remove noise and keep what matters - Generates a HTML technical report using an LLM (OpenAI GPT-4.1) - Detects whether Code nodes exist - If Code nodes exist, analyzes their logic and adds an extra technical section - Creates a final Google Docs document inside a Google Drive folder
