Formatted XML appears here
Paste XML above to format it instantly.
Format, indent, and minify XML right in your browser. Paste messy or single-line XML and get clean, properly nested output — or compress it back down for transport. The tool also checks that your XML is well-formed and points out syntax errors as you type.

Beautify vs. minify
Two directions for the same document.
| Mode | Input | Output |
|---|---|---|
| Beautify | <a><b>1</b></a> | <a> <b>1</b> </a> |
| Minify | <a> <b>1</b> </a> | <a><b>1</b></a> |
Common XML mistakes
- Unclosed tags. Every
<tag>needs a matching</tag>or must self-close as<tag/>. - Unescaped characters.
&,<, and>inside text must be written as&,<, and>. - Multiple root elements. A well-formed document must have exactly one top-level element wrapping everything else.
Frequently asked
Does it validate my XML?
Yes. As you type, the tool parses your XML with the browser's built-in parser and reports whether it's well-formed, flagging the error if it isn't. Note that well-formed means correct syntax — it does not check against a DTD or XSD schema.
What's the difference between beautify and minify?
Beautify adds line breaks and indentation so nested elements are easy to read. Minify strips the whitespace between tags to make the file as small as possible for transport or storage.
Is my XML uploaded anywhere?
No. Formatting and validation happen entirely in your browser using its native XML parser. Your data never leaves your device.
