Web URL & Data Extractor
Extract all URLs from websites, sitemaps, or HTML source — in single or bulk mode. Export to CSV, Excel, or copy directly for Sheets.
Three Modes
1. Sitemap / URL Mode
Enter any URL (sitemap or regular page). The tool fetches the content via a CORS proxy and extracts all <loc> tags (for XML sitemaps) or all href and src attributes (for HTML pages).
2. Paste HTML / Text Mode
Open the target page in your browser, right-click → View Page Source, select all (Ctrl+A), copy, and paste into this tool. All https:// and http:// URLs are extracted automatically.
3. Bulk URL List Mode
Paste a list of URLs (one per line). The tool parses each URL into structured columns: domain, path, query string, and file type. Useful for auditing existing URL lists or preparing data for analysis.
Exporting Results
- Copy for Sheets — copies tab-separated data. Paste directly into Google Sheets or Excel — columns appear automatically.
- CSV — comma-separated file, importable in any spreadsheet tool.
- Excel (.xls) — tab-separated with UTF-8 BOM, opens cleanly in Excel.
- Copy URLs only — plain list of URLs, one per line.

How it works
Each platform has different rules: character limits, allowed characters (letters, numbers, dots, underscores, hyphens), and minimum lengths. The tool automatically adapts your brand name to each platform's rules — removing invalid characters, truncating if necessary, and flagging when the result is too short to be valid.
