Why format XML?
Compact or poorly indented XML is hard to debug. A formatter adds predictable nesting so you can scan elements, attributes, and hierarchies quickly during code review or API testing.
Clean XML also makes diffs clearer in pull requests and helps catch structural mistakes before they reach production.
Beautify, minify, and validate
Beautify when editing configuration or SOAP responses. Minify when you need a smaller payload for storage or transport. Validate when you suspect unbalanced tags or malformed markup.
Choose 2-space or 4-space indentation to match your project conventions, then copy the output with one click.
How to use this XML formatter

Privacy-first by default
XML never leaves your browser. Formatting and validation are local-only—nothing is uploaded or stored remotely.
Frequently Asked Questions
What does an XML formatter do?
An XML formatter beautifies XML by adding consistent indentation and line breaks so nested elements are easier to read and review.
Can I minify XML too?
Yes. Use Minify XML to remove unnecessary whitespace and produce a compact XML string.
Is my XML sent to a server?
No. Formatting, minifying, and validation all run in your browser. Your XML is never uploaded.
