n8n-workflows/generate_documentation.py
Rex Lorenzo fff6919ffb Add comprehensive Python-based n8n workflow documentation generator
Creates an automated documentation system that analyzes n8n workflow JSON files
and generates interactive HTML documentation with detailed insights.

Features:
• Static analysis of 2053+ workflow files with intelligent categorization
• Interactive HTML interface with search, filtering, and statistics dashboard
• Automatic trigger type detection (Manual, Webhook, Scheduled, Complex)
• Complexity classification and integration detection
• AI-generated workflow descriptions and metadata extraction
• Responsive design with dark/light themes and WCAG accessibility
• JSON viewer with copy/download functionality

Technical Implementation:
• WorkflowAnalyzer class processes all JSON files in workflows/ directory
• Generates self-contained HTML with embedded analysis data
• No external dependencies - uses only Python standard library
• Clean, optimized code with proper type hints and error handling
• Performance optimized for large workflow collections

Usage:
1. Run: python3 generate_documentation.py
2. Open: workflow-documentation.html in browser
3. Browse comprehensive workflow documentation with full analysis

Code Quality:
• Optimized Python with dictionary-based lookups and constants
• Clean CSS without redundant declarations
• Comprehensive README with usage instructions
• Removed superseded documentation files
