What is a XML Formatter?
Format, beautify, and validate messy XML files with custom indentation and instant syntax error detection. This tool re-indents and organizes code according to standard style conventions while checking for syntax validity. Everything executes 100% inside your browser, guaranteeing zero latency and complete privacy for API keys, user tokens, and confidential database schemas.

| Indentation | Select indentation width or minify to remove all unnecessary whitespace. |
| Collapse short content tags | Keeps short text content inline (e.g. <title>Text</title>) rather than breaking into 3 lines. |
Frequently Asked Questions

Can I minify XML with this tool?
Yes. Select 'Minified (Compact)' in the Indentation option to strip comments and whitespace.
