What does the XML Sitemap Validator check?

It checks sitemap XML format, URL entries, index files, lastmod values, and common issues that can make search engines ignore or misread a sitemap.

Do I need to upload a file to validate a sitemap?

No. You can validate a sitemap URL directly, which is usually the fastest way to check the published file search engines will crawl.
