About this tool

XML is older than JSON and still everywhere: RSS and Atom feeds, SOAP web services, configuration files for build tools, SVG graphics, Microsoft Office documents under the hood, the underlying format of many enterprise APIs. Reading XML by hand is painful when it arrives without whitespace, so this tool pretty-prints any XML you paste with proper indentation, one element per line, attributes preserved as-is. It also minifies XML when you need to send a compact version, and it detects unbalanced tags so you know if the document is well-formed before downstream parsing fails. The implementation uses the browser's built-in DOMParser, which means the formatter sees the document exactly the way a real XML parser would. If your input is malformed, the tool surfaces the parser error rather than producing junk. Pasted content stays in your browser; nothing is uploaded.

Frequently asked questions

No. The tool checks that the document is well-formed XML (proper nesting, matched tags, valid syntax) but it does not validate against an external XSD or DTD. For schema validation, use a dedicated XML validator with your schema file.
