It checks your sitemap XML is well-formed and follows the sitemap protocol — valid URL entries, correct tags, and proper structure that Google can crawl.
How many URLs can I validate?
Any size sitemap can be pasted and checked — validation runs in your browser so there is no server limit.
Is my sitemap uploaded anywhere?
