What is an XML formatter?

An XML formatter re-indents XML (eXtensible Markup Language) so its element nesting is easy to read. It's used for configuration files, RSS/Atom feeds, SVG, SOAP messages, and data exchange documents — anywhere structured markup needs to be reviewed or debugged.

Frequently Asked Questions

Does it validate the XML too?

Yes — it must parse your XML to format it, so malformed XML is reported with an error. For a dedicated check, use the XML Validator.

Are comments and CDATA kept?

Yes — comments, CDATA sections, and processing instructions are preserved in the formatted output.

Is it free and private?

Yes — it's 100% free with no signup, and everything runs locally in your browser, so your data is never uploaded to a server.
