What this tool does

Paste any XML and the tool reformats it with consistent indentation. If the XML is malformed, you get an error message pointing to the problem. Choose between 2-space and 4-space indentation depending on your project's style.

Where XML still shows up

SOAP APIs, Maven pom.xml files, Android layouts, SVG files, RSS feeds, XHTML, and legacy enterprise integrations. XML isn't going anywhere. When you're debugging a minified SOAP response or reviewing an SVG path, readable formatting makes the difference between guessing and actually understanding the structure.

Common XML mistakes

Unclosed tags or mismatched tag names. Missing the XML declaration. Unescaped special characters like & (should be &) and < inside text nodes. Attributes without quotes. Self-closing tags missing the trailing slash. This formatter catches structural issues so you can fix them before they cause runtime errors.
