n8n Workflow: Google Sheets Scraping Pipeline

How This Blueprint Works

Turn Google Sheets into a web scraping command center. This workflow reads a list of target URLs from a Google Sheet, visits each page, extracts specified HTML elements, and writes the scraped data back to the sheet.

The Execution Sequence

1. Schedule Trigger Node — Configured to run at your preferred interval. Also supports manual execution for ad-hoc scraping tasks. Ideal for daily price monitoring, competitor tracking, or content aggregation.
2. URL Reader Node — Reads a Google Sheet with columns: url, css_selector, attribute (text, href, src), label. Each row defines one scraping target. Uses Header Row mode with the Sheets node for clean column mapping.
3. Web Scraper Node — An HTTP Request node that fetches each URL sequentially with a custom User-Agent header (to avoid blocks), follows redirects (max 5), and has a 30-second timeout. Returns raw HTML.
4. Data Extractor Node — A Code node that parses the HTML response. Uses string-based extraction (regex patterns between markers) or CSS selector parsing to extract content from the targeted elements defined in the sheet.
5. Scrape Logger Node — Writes scraped results back to the Google Sheet: the extracted text, a timestamp, and HTTP status. Failed URLs get a red status indicator and the error message for debugging.

FAQ

What if the target website blocks scrapers?

Add rotating User-Agent headers, introduce random delays between requests (2-5 seconds), and use the HTTP Request node with proxy support. For heavily protected sites, use the Puppeteer node for headless browser scraping.

How many URLs can I scrape per run?

Limited only by your n8n instance resources and target site rate limits. For 100+ URLs, use the SplitInBatches node to throttle concurrent requests (batch size of 5 is recommended).

Can I scrape JavaScript-rendered pages?

Yes. Replace the HTTP Request node with the Puppeteer node. It launches a headless Chromium browser that executes JavaScript. Configure waitForSelector to ensure dynamic content loads before scraping.
