{"workflow":{"id":14093,"name":"Generate C API HTML docs from Google Drive headers with GPT-4o and Gmail","views":27,"recentViews":1,"totalViews":27,"createdAt":"2026-03-16T17:55:53.272Z","description":"\n## ๐Ÿš€ Overview\n\nThis n8n workflow automatically generates **professional API documentation from C header (`.h`) files** using AI.\n\nIt scans a Google Drive folder for header files, extracts the source code, sends it to **GPT-4o** for structured analysis, and generates a **beautiful HTML documentation page**. The final documentation is uploaded back to Google Drive and a completion email is sent.\n\nThis workflow is ideal for **embedded systems teams, firmware engineers, and SDK developers** who want an automated documentation pipeline.\n\n---\n\n# โœจ Key Features\n\nโšก Fully automated documentation generation \n๐Ÿ“ Reads `.h` files directly from **Google Drive** \n๐Ÿค– Uses **AI to analyze C APIs and extract documentation** \n๐Ÿ“‘ Generates **clean HTML documentation** \n๐Ÿ“Š Documents functions, types, enums, and constants \n๐Ÿ” Processes files **one-by-one for reliability** \nโ˜๏ธ Saves generated documentation back to **Google Drive** \n๐Ÿ“ง Sends a **completion email notification**\n\n---\n\n# ๐Ÿง  What the AI Extracts\n\nThe workflow automatically identifies and documents:\n\n- ๐Ÿ“˜ **Overview** of the header file\n- ๐Ÿ”ง **Functions**\n - Signatures\n - Parameters\n - Return values\n - Usage examples\n- ๐Ÿงฉ **Enumerations**\n- ๐Ÿงฑ **Data Types & Structures**\n- ๐Ÿ”ข **Constants / Macros**\n- ๐Ÿ“ **Developer Notes**\n\n---\n\n# ๐Ÿ–ฅ Generated Documentation\n\nThe output is a **clean developer-friendly HTML documentation page** including:\n\n- ๐Ÿงญ Sidebar navigation\n- ๐Ÿ“Œ Function cards\n- ๐Ÿ“Š Parameter tables\n- ๐Ÿ’ป Code examples\n- ๐ŸŽจ Professional developer layout\n\nPerfect for:\n\n- Developer portals\n- SDK documentation\n- Internal engineering documentation\n- Embedded system libraries\n\n---\n\n# โš™๏ธ Workflow Architecture\n\n| Step | Node | Purpose |\n|-----|-----|--------|\n| 1 | โ–ถ๏ธ Manual Trigger | Starts the workflow

run this workflow you need:\n\n๐Ÿ”น **Google Drive OAuth2 credentials** \n๐Ÿ”น **OpenAI API credentials** \n๐Ÿ”น **Gmail credentials**\n\n---\n\n# ๐Ÿ›  Setup Guide\n\n## 1๏ธโƒฃ Configure Google Drive\n\nCreate two folders.\n\n**Source folder**\n\n**Output folder**\n\nUpdate the folder IDs in the nodes:\n\n- `Get all files from folder`\n- `Save documentation to Google Drive`\n\n---\n\n## 2๏ธโƒฃ Configure OpenAI\n\nAdd an **OpenAI credential** in n8n.\n\nModel used:\n\nThe model analyzes C header files and returns structured API documentation.\n\n---\n\n## 3๏ธโƒฃ Configure Gmail\n\nAdd a **Gmail OAuth credential**.\n\nUpdate the recipient address inside:\n\n---\n\n## โ–ถ๏ธ Run the Workflow\n\nClick **Execute Workflow**.\n\nThe workflow will:\n\n1๏ธโƒฃ Scan the Google

be extended with several enhancements:\n\n### ๐Ÿ“„ PDF Documentation Export\nAdd a step to convert the generated HTML documentation into **PDF files** using tools such as:\n\n- Puppeteer\n- HTML-to-PDF services\n- n8n community PDF nodes\n\nThis allows teams to distribute documentation as **downloadable reports**.\n\n---\n\n### ๐Ÿ” Local AI for Security (Ollama / Open-Source Models)\n\nInstead of using the OpenAI node, the workflow can be modified to run **fully locally** using AI models such as:\n\n- **Ollama**\n- **Open-source LLMs (Llama, Mistral, CodeLlama)**\n\nThese models can run **on your own server**, which provides:\n\n๐Ÿ”’ Better **data privacy** \n๐Ÿข **No external API calls** \nโšก Faster responses on local infrastructure \n๐Ÿ›ก Increased **security for proprietary source code**\n\nThis can be implemented in n8n using:\n\n- **HTTP Request node โ†’ Ollama API**\n- Local AI inference servers\n- Private LLM deployments\n\n---\n\n### ๐Ÿ“š Multi-Language Documentation\n\nThe workflow could also support additional languages such as:\n.c\n.cpp\n.hpp\n.rs\n.go\n","workflow":{"meta":{},"name":"API Documentation โ€”
