Validate Sitemap XML Online

Paste sitemap XML to check structure, URL format, and duplicates. Does not fetch live sitemaps or verify HTTP status.

Paste only — cannot fetch live URLs.The sitemap validator analyzes content you paste into the box. Browsers block websites from loading other sites' HTML (CORS), so we cannot enter a URL and pull your page automatically. Copy HTML from View Source (Ctrl+U / Cmd+Option+U), your CMS, or a saved file.

Also does not check whether listed URLs return 200 — that requires a server-side crawler.

    Frequently asked questions

    Can this fetch my sitemap from a URL?

    No. Paste the XML content. Browsers cannot fetch sitemap files from other domains due to CORS.

    Does it check if URLs return 200?

    No. It validates XML structure, URL format, and duplicates only. Checking HTTP status requires a server-side crawler.

    What sitemap formats are supported?

    Standard sitemaps and files per sitemaps.org.

    Is my sitemap uploaded?

    No. Validation runs entirely in your browser.
