About Sitemap XML Linter

Developer and writing chores should stay private when the text is sensitive. This sitemap validator page gives you sitemap xml linter without the clutter: lint sitemap.xml structure, count URLs, and flag common issues — entirely in your browser.

What Sitemap XML Linter does

Lint sitemap.xml structure, count URLs, and flag common issues — entirely in your browser. Paste only the segment you need so results stay easy to scan. For encoding tools, round-trip with the matching encode/decode pair when you want to verify.

Where your data goes

Sitemap XML Linter runs in your browser for this job. Your sitemap.xml is not uploaded to FileToolsHub servers for the conversion itself, which matters when you are dealing with private notes, drafts, or local files.

Tips for accurate sitemap validator results

Watch for whitespace, wrapping quotes, and character set issues. If the tool errors, simplify the input and retry. Use related utilities below when your workflow needs a second transform.
