About XML Formatter and Validator
XML Formatter and Validator parses XML before producing indented or minified output, helping you distinguish invalid markup from formatting problems.
Elements, attributes and text content stay local in the browser while the result becomes easier to review or copy.

- Beautify compact API or feed XML.
- Validate closing tags and attribute syntax.
- Minify an XML fixture for a request or test.
How to use XML Formatter and Validator

Real-world examples
