What is an XML formatter?
XML (eXtensible Markup Language) is widely used for configuration, SOAP APIs, RSS feeds, sitemaps and document formats. It's often stored or transmitted minified — all on one line — which is hard to read. An XML formatter (or "beautifier") re-indents it into a clean, nested tree so you can actually see the structure. This tool also validates your XML and reports where it's malformed.
How to use it
- Paste your XML into the Input box on the left.
- Click Beautify (or press
Ctrl/⌘+Enter). Pick your indentation. - Copy the clean result from the Output box.
Use Minify to collapse the XML back down to a single compact line.
Is my data safe?
Yes. All formatting happens locally in your browser — your XML is never uploaded to any server, and the tool works offline once loaded.
