XML formatter
Format XML for readability, validate XML syntax and well-formedness, or minify XML to compact output — useful for API responses, configuration files, and data exchange formats.

SOAP APIs return XML responses that can be hard to read in raw form. Paste the response body into the formatter to expand the nested elements, then validate to confirm the XML is well-formed before processing it in code.
The tool parses the input as XML, validates it for well-formedness, and serializes valid data with the selected indentation or minified output. Parsing errors are reported with the position of the first invalid character.
Avoid pasting XML that contains sensitive data, authentication tokens, or private records. For ordinary XML snippets, the workflow is browser-based.
The formatter checks XML syntax and well-formedness. It does not validate against XSD schemas, DTD definitions, or custom business rule constraints.
