Sitemap URL extractor

What the sitemap URL extractor does

An XML sitemap is the closest thing to a machine-readable table of contents for a website — but reading one by hand is miserable, and most real-world sitemaps are actually sitemap indexes that point to dozens of child sitemaps. This tool flattens all of that into one clean list: enter a bare domain and we discover the sitemap from robots.txt (falling back to guessing /sitemap.xml), or paste a sitemap URL directly. Every child sitemap is fetched and expanded, and you get the full URL list with each entry's lastmod date.

Why you'd want every URL as a flat list

• Site migrations — export the old site's URLs to CSV and use it as the source column of your redirect map. Missing a URL here means a 404 after launch.
• Content inventory — the per-section counts (first path segment) instantly show how a site's content is distributed: 400 blog posts, 12 landing pages, 3 docs.
• Competitor research — a competitor's sitemap is public. Sorting by newest lastmod shows what they published or updated most recently.
• Bulk audits — feed the exported list into any crawler, indexing checker, or spreadsheet workflow.

Does it handle sitemap indexes?

Yes — if the URL you enter (or the one discovered from robots.txt) is a <sitemapindex>, we fetch each child sitemap and merge the results, expanding up to 50 child sitemaps per run.

How many URLs can it extract?

Up to 10,000 URLs per run (and 50 child sitemaps). Larger sitemaps are truncated with a clear warning. The on-page table shows the first 1,000 rows for speed, but the copy and export buttons always include every extracted URL that matches your filter.

Is the URL list stored anywhere?

No. The sitemap is fetched, parsed, and returned to your browser — nothing is saved. To have your sitemap cross-checked against your live pages continuously, that's what siteOS does — or run a one-off check with the sitemap validator.
