Frequently asked questions

Does it validate XML?

It checks that the structure is correct: tags properly opened, closed and nested, and comments and CDATA complete. It does not validate against an XSD schema or DTD.

Are comments and declarations kept?

Yes, by default comments, CDATA and the initial declaration are kept. You can remove comments by unchecking the box.

Is my file uploaded to a server?

No. Formatting happens in your browser, so you can work with private or confidential documents.

Can I use it for HTML?

For HTML, the HTML formatter is better, since it tolerates unclosed tags like br or img. XML is stricter and would flag them as errors.
