AI Web Scraper with HTML Fallback

AI Web Scraper with HTML Fallback

# Extract web data via AI vision with HTML fallback, save results to Google Sheets

This automation extracts structured data from websites using AI-powered screenshot analysis with a fallback to HTML scraping when visual data is insufficient. It´s ideal for cases where content is obscured, dynamically loaded, or partially inaccessible. The workflow combines Google Gemini’s vision capabilities with ScrapingBee’s reliable HTML access, ensuring high accuracy and resilience.

## Who it´s for
- Marketers collecting pricing and promotion data from competitor sites
- Analysts regularly scraping e-commerce platforms
- Developers building AI-driven price monitoring systems
- E-commerce owners automating product data collection

## What the automation does
- Triggered manually or via API call
- Reads URLs from Google Sheets
- Captures a screenshot and sends it to Google Gemini for visual analysis
- If visual extraction fails, automatically fetches HTML via ScrapingBee
- Converts HTML to Markdown to reduce token usage before reprocessing
- Structures output as JSON and writes results back to Google Sheets
- Ensures reliability through fallback logic between vision and HTML parsing

## What´s included
- Ready-to-use n8n workflow with LangChain agent
- Trigger logic: manual execution and API-based start
- Integrations with Google Sheets, Google Gemini, and ScrapingBee API
- Basic text instructions for setup and adaptation

- Google Gemini API key
- ScrapingBee API key
- Google Sheets access with read/write permissions

## Benefits and outcomes
- Automatic data extraction even from protected or partially visible pages
- Time savings in competitive intelligence gathering
- Higher parsing accuracy via dual verification (vision + HTML)
- Reduced AI token costs through HTML-to-Markdown preprocessing
- Centralized result storage in Google Sheets
- Scalability for regular monitoring (e.g., weekly reports)
