XML Formatter & Validator
Runs locally in your browserBeautify, minify, and validate XML locally
Runs locally in your browser. Uploaded XML is treated as text and is never rendered.
What is an XML formatter and validator?
This tool beautifies, minifies, and checks XML well-formedness without converting it to another format. It preserves namespaces, attributes, comments, CDATA, processing instructions, and mixed-content text while processing everything locally in your browser.
How to use it
Paste XML or upload a compatible text file, choose Document or Fragment mode in Advanced, then select Beautify, Minify, or Validate. Copy the result or download it as an .xml file.
Validation and preservation
Validation checks XML syntax and well-formedness, not XSD or schema rules. Formatting stays conservative around mixed content and whitespace-only values; external entities are never fetched and SVG is handled only as text.
