How it works
This tool parses your XML with the browser XML parser, validates it, and then outputs a readable indented version.
Examples
- <root><a>1</a></root> → formatted with line breaks and indentation
- Nested elements → each level indented consistently
- Invalid tag nesting → parse error shown instead of output

FAQ

The tool shows a parse error and does not generate formatted output until the XML is valid.
- Is my XML stored?
No. Formatting runs locally in your browser and is not stored or transmitted.
