XML Formatter
Pretty-print, minify, or validate XML payloads in your browser. Useful for inspecting SOAP responses, debugging Mule transformations, or cleaning up legacy enterprise XML.
What this tool does
Format parses your XML with the browser's native DOMParser,
then walks the tree to re-emit it with consistent indentation. Comments, CDATA blocks,
processing instructions, and self-closing tags are preserved.
Minify strips whitespace between elements without touching whitespace inside text content, so your payload stays semantically identical but becomes the smallest valid wire format.
Validate reports the first XML well-formedness error with a line number. Note that this does NOT validate against an XSD schema — it only checks well-formedness (matched tags, valid entities, etc).
