Does the formatter validate my XML?

Yes. The tool checks for well-formedness errors like unclosed tags and mismatched attributes.

Yes. The Minify option removes all whitespace to produce compact single-line XML.

What is the difference between pretty-printing and minifying?

Pretty-printing adds indentation for human readability. Minifying removes all whitespace to reduce file size.

The tool handles XML in the browser. Very large files over 10MB may be slow depending on your device.

Beautify, format, validate, or minify raw XML code instantly. View active parse validation error lines client-side.

Input XML:

Indent Size:

Type or paste raw XML data inside the **Input XML** editor.
Specify your alignment preference (2 spaces, 4 spaces, or standard Tab character indentation).
Click **Format XML** — the browser will pass the string through the `DOMParser` object to build a clean XML tree.
If parsing succeeds, it formats the tree recursively. If it fails, the parser returns exact validation error locations.
