XML formatter and validator: frequently asked questions
Does it validate against a schema?
No. It checks that the XML is well-formed (tags opened and closed in the right order), not that it matches an XSD.
Is my XML uploaded?
No. Formatting runs in your browser.
Are comments and CDATA kept?
Yes. Comments, CDATA sections and the XML declaration are preserved.
Can I format a sitemap?
Yes. Paste the sitemap XML to read it more easily or check it is well-formed.
Why does minify help?
Removing whitespace between tags makes files smaller to send, for example in APIs.
What does “closing tag does not match” mean?
A tag was closed in the wrong order, e.g. <a><b></a></b>. Fix the nesting.
Does it change my data?
Only whitespace between tags. Text inside elements is kept.
Can I convert XML to JSON?
Not yet. That converter is on our roadmap.
Is there an API for this tool?
