XML Formatter is a 100% free, browser-based utility that enables you to beautify, minify and validate xml documents. Unlike traditional cloud converters, all processing executes locally on your device with zero server uploads, delivering immediate results and ironclad data privacy.
About the XML Formatter
The XML Formatter makes dense XML readable by putting each element on its own line with consistent indentation, and minifies it again when you need a compact version. It checks that the document is well-formed using your browser's XML parser and reports the problem if a tag is not closed or an attribute is malformed.
It works with any XML dialect, including SOAP envelopes, RSS and Atom feeds, sitemaps, Android layouts, Maven POM files and SVG images.

Frequently asked questions
Does it validate against a schema (XSD)?
No. It checks that the XML is well-formed (correct nesting, quoting and closing tags). Schema validation against an XSD or DTD is not performed.
Are comments and CDATA kept?
Yes. Comments, CDATA sections and processing instructions such as <?xml version="1.0"?> are preserved.
Will formatting change text content?
Whitespace-only text between elements is reformatted. Text inside elements that contain other text is kept as is.
