About this XML formatter

This tool takes compact or minified XML and adds proper indentation (2 spaces per level) to make it readable. It also handles minification — stripping all whitespace between tags — for production use. All processing happens in JavaScript in your browser.

API access

Format via API: POST /api/v1/datatools/format/xml with body {"input": "your xml"}

Minify via API: POST /api/v1/datatools/minify/xml

Does this validate XML? +
This formatter structures XML visually but does not perform full XML schema validation. For schema validation against DTD or XSD, you would need a dedicated XML validation tool.
Does it handle XML namespaces and attributes? +
Yes — attributes and namespace declarations within tags are preserved as-is. The formatter only restructures the whitespace between tags, not the content within them.
