About XML Formatter
XML formatting normalizes indentation and breaks tags onto their own lines so deeply nested documents are readable. Validation uses the browser's built-in DOMParser to confirm tags match and syntax is well-formed.
This tool runs locally. RSS feeds, SVG files, SOAP envelopes, sitemaps — all parse and format the same way.

Frequently asked
Is my XML sent to a server?
No. Formatting and validation run entirely in your browser using the native DOMParser.
Does it validate against an XSD schema?
It checks well-formedness (matched tags, valid syntax) but not XSD/DTD schema validation.
Will it preserve CDATA and comments?
Format preserves CDATA. Minify strips comments. Both keep CDATA blocks intact.
What about SVG, RSS, sitemaps?
All XML-based formats work — SVG, RSS, Atom, sitemaps, SOAP envelopes.
