XML Sitemap Validator Lite
Paste XML sitemap content to catch parse errors, duplicate URLs, invalid loc values, and bad lastmod dates before submission.
Catch sitemap structure problems quickly
A sitemap can look fine in a browser and still contain bad data: malformed XML, missing loc tags, duplicate URLs, invalid URL strings, or lastmod values that do not follow the expected date format.
This is a fast first pass before Search Console, Bing Webmaster Tools, or a deeper crawl. Paste sitemap XML, review the messages, and fix the source generator if an issue repeats.
Private XML parsing
Your sitemap content stays local.
Frequently Asked Questions
What does this sitemap validator check?
It checks whether XML parses, finds loc entries, flags invalid URLs, duplicate URLs, and invalid lastmod dates.
Is it a complete search-engine validator?
No. It is a lightweight structural check. Use Search Console or a full crawler for final validation.
Can it validate sitemap index files?
It can extract loc tags from sitemap indexes, but it does not fetch child sitemaps.
Is my XML uploaded?
No. Parsing and checks run locally in your browser.
