What does formatting XML mean?

Formatting (or pretty-printing) adds consistent indentation and line breaks so the tree structure is easy to read. Minifying does the opposite — it removes all unnecessary whitespace to reduce file size.

Does it validate my XML?

Yes — the tool uses the browser's built-in DOMParser, which reports a parse error if the XML is malformed. You will see a red error message with the problem description.

Is my XML sent anywhere?

No. All processing happens in your browser using the native DOMParser and XMLSerializer APIs. Nothing leaves your machine.

What XML features does it support?

It handles elements, attributes, text nodes, CDATA sections, comments, and processing instructions — standard well-formed XML. It does not validate against an XSD or DTD.
