XML formatter

What it does

The Carbide XML formatter takes flat or minified XML and pretty-prints it into a clearly indented, easy-to-read tree, and can collapse it back to a compact single line whenever you need a smaller payload. It is free, runs entirely in your browser, and is offline-friendly once loaded, so your documents stay on your device and are never sent to a server. Paste a feed, a config file, a SOAP message, or any XML snippet into the editor, choose beautify to reveal the nesting of elements and attributes, or minify to remove comments and whitespace between tags. Syntax highlighting helps you follow the structure and spot mismatched tags while you edit, and you can copy the result or download it as an .xml file in one click. Built on a real XML formatter engine, it handles attributes, namespaces, and nested elements gracefully, making it a quick, private way to clean up exported data, inspect API responses, or prepare XML for sharing and debugging.

Frequently asked questions

Is the XML formatter free to use?

Yes. It is completely free with no account required and no limit on the size or number of XML documents you format.

Is my XML uploaded to a server?

No. The formatter processes your XML on-device in the browser, so your documents never leave your computer and it works offline after loading.

Can it both beautify and minify XML?

Yes. Beautify pretty-prints the document with indentation, while minify removes comments and whitespace between tags for a compact result.

Does it handle attributes and namespaces?

Yes. The XML formatter preserves attributes, namespaces, and nested elements, so your document stays valid after formatting.
