XML Formatter

The formatter parses your XML and reformats it with consistent indentation, proper nesting, and clean alignment. It handles elements, attributes, text nodes, CDATA sections, comments, and processing instructions. The result is properly indented XML that clearly shows the document structure.

Yes — the tool checks XML well-formedness (proper nesting, matching tags, valid characters, proper attribute quoting). It reports specific error locations with line and column numbers. Note that it validates structure, not schema compliance — for DTD or XSD validation, you need schema-specific tools.

Yes — the formatter correctly preserves namespace declarations (xmlns attributes), namespace prefixes, and default namespaces. Formatting does not alter namespace bindings or prefix assignments — the document remains semantically identical after formatting.

Choose between 2 spaces, 4 spaces, or tabs for indentation. You can also configure whether attributes wrap to new lines (useful for elements with many attributes) and whether empty elements use self-closing tags (<br/>) or paired tags (<br></br>).

Yes — toggle minify mode to remove all unnecessary whitespace, reducing the XML to a single line. This is useful for API payloads, configuration files, or any context where human readability is not needed and smaller payload size matters.
