Features

Limitations
- URL mode depends on browser CORS — many sites block direct fetches; paste HTML or upload files instead
- Does not bypass login, paywalls, CAPTCHA, or anti-bot protection
- Email and phone extraction is pattern-based only — not verified
- Very large HTML documents may slow extraction; use the result limit option
Use Cases
- Debugging API JSON responses

- Validating configuration files before deploy
Tips
- Start with sample data to learn selectors

- If URL fetch fails, paste saved page HTML instead
Frequently Asked Questions
What is a web scraper?
A web scraper extracts structured information from HTML — such as product names, prices, links, or table rows — using selectors or parsers. DataForge Web Scraper runs entirely in your browser for HTML you provide or can fetch.
Is DataForge Web Scraper free?
Yes. DataForge Web Scraper is free on ToolsCorner with no account required.
Can I scrape any website by URL?
No. Browser security (CORS and site policies) often blocks direct URL fetching. If a URL fails, save the page HTML and paste or upload it — extraction works the same on the HTML content.
Why does URL scraping sometimes fail?
Websites may block cross-origin requests, require authentication, or return errors. This tool does not bypass those restrictions. Use HTML paste or file upload for blocked pages.
What is CSS selector extraction?
You define CSS selectors (e.g. .product-title) and extraction types (text, href, src). The engine matches elements in your HTML and returns structured rows you can export.
Can I extract tables from HTML?
Yes. Use the Extract Tables quick mode to detect HTML tables, preview headers and rows, and export selected tables to CSV or JSON.
Can I export scraped data to CSV?
Yes. Export CSV, JSON, TSV, TXT, or HTML table formats. CSV includes proper escaping and UTF-8 BOM for Excel compatibility.
Is my HTML uploaded to a server?
When you paste HTML or upload files, processing happens locally in your browser. URL mode fetches only from your browser — ToolsCorner has no backend that stores your data.
Does the scraper bypass website security?
No. It does not bypass CAPTCHA, Cloudflare, login walls, paywalls, robots.txt, or rate limits. It is a lawful utility for user-provided or publicly accessible content you can load into the tool.
What data can the tool extract?
Custom fields via CSS selectors, plus links, images, headings, page metadata, JSON-LD, HTML tables, emails (pattern-based), and phone numbers (pattern-based, unverified).
