Sitemap Validator

Validate sitemap XML locally: well-formedness, absolute <loc> URLs and W3C lastmod dates. Nothing is fetched.

About this tool

Paste your sitemap and get per-entry findings: missing loc elements, non-absolute URLs and malformed lastmod dates. Purely local — the file is never fetched or submitted.

How to use the Sitemap Validator tool

  1. Paste the sitemap XML. Straight from your sitemap file.
  2. Validate. Well-formedness is checked first, then each URL entry.
  3. Fix and re-run. Every finding names the URL entry it applies to.

Supported formats

Input

  • Plain text or file input

Output

  • Converted or analysed output

Inputs are validated before anything is processed. Invalid values and unsupported files are rejected with a clear error instead of failing silently.

Frequently asked questions

Does it submit the sitemap?

No. Validation only; submission belongs in Search Console.

Which date format is required?

W3C format — YYYY-MM-DD or a full timestamp.

Are sitemap indexes supported?

The validator reads url entries; index files report as empty.

No account is required and no file is ever uploaded. See the privacy policy for details about analytics and the limited data this site stores.

Known limitations

  • URL reachability is not checked — this validates structure only.
