XML Formatter
Beautify messy XML with clean indentation, or minify it to a single line — with well-formedness checking, all in your browser.
Make XML readable again
XML that arrives minified — one long line with no spacing — is nearly impossible to read or debug. This formatter re-indents it into a clean, nested structure so you can actually see the hierarchy of elements. Working the other way, it can also collapse well-formatted XML back down to a single line for transport or storage where size matters.
It uses the browser's own XML parser to check that your document is well-formed, flagging unbalanced or malformed tags before they cause problems downstream. Formatting only touches the whitespace between elements — your tags, attributes, and content stay exactly as they were. Paste, beautify or minify, and copy the result.
Private and instant
Everything runs in your browser, so sensitive documents never leave your device.
Frequently Asked Questions
What does the XML formatter do?
It pretty-prints XML by adding consistent indentation and line breaks so nested elements are easy to read. It can also minify XML back to a single line.
Does it validate my XML?
It checks that the XML is well-formed using the browser’s parser and reports an error if tags are unbalanced or malformed, so you catch structural problems.
Will it change my data?
No. Formatting only adjusts whitespace between elements. Your element names, attributes, and text content are preserved exactly.
Is my data private?
Yes. Formatting runs entirely in your browser — nothing is uploaded or stored.
