About this tool

XML that comes from a web service or configuration file is often minified for transport efficiency. Formatting adds the indentation that makes the tag hierarchy readable; minifying removes it again for production use.

The formatter parses the XML first, so it will report an error if the document is not well-formed. This doubles as a quick validity check.

How to use it

Paste your XML into the left panel.
Choose Format (to indent) or Minify (to compress).
For formatted output, pick 2 or 4 spaces of indentation.
Copy the result.

Common problems

Parse error on valid-looking XML.: Common causes: missing closing tag, an unescaped < or & in a text node, or two root elements. XML requires exactly one root element and strict escaping.
