n8n workflow for scraping vehicle manual PDFs and uploading them to cloud storage.
Automation pipeline for discovering, validating, and collecting vehicle manual PDFs from indexed web sources.
This project uses n8n automation workflows to scrape vehicle manual PDFs across multiple manufacturers and year ranges, validate extracted files, and upload them to cloud storage automatically.
The workflow is designed to automate manual document collection and reduce repetitive data gathering.
• Automated vehicle manual scraping
• Supports multiple manufacturers and year ranges
• Regex-based PDF extraction from HTML pages
• Batch processing with delays to prevent server overload
• Validation of manual year ranges (2000–2026)
• Automatic cloud upload using Google Drive integration
The automation pipeline follows these steps:
- Generate manufacturer and year catalog URLs
- Fetch index pages from the manual database
- Extract detail page links using regex filters
- Parse detail pages to locate PDF manual files
- Validate manual metadata and year range
- Download PDF documents with retry handling
- Upload verified files to cloud storage
- n8n Workflow Automation
- JavaScript Function Nodes
- HTTP Request Nodes
- Regex Parsing
- Google Drive API
- Cloud Storage Integration
- Import the JSON workflow into n8n
- Reconnect your Google Drive credentials
- Replace the target folder ID
- Run the workflow using the Manual Trigger
- Support additional vehicle manufacturers
- Add duplicate file detection
- Store metadata in a database
- Schedule automated runs with cron triggers
- Implement monitoring and logging
