XML Formatter & Validator is a free online tool that helps developers format, beautify, minify, and validate XML documents instantly. All processing happens in your browser — no data is ever sent to a server, ensuring complete privacy and security.
XML (eXtensible Markup Language) is a markup language used for storing and transporting data. Formatting XML makes it human-readable with proper indentation and line breaks, which is essential for debugging, reviewing configurations, and sharing data with others.
Yes, absolutely. All processing happens entirely in your browser using JavaScript. Your XML data is never sent to any server, ensuring complete privacy and security.
Format (Beautify) adds indentation and line breaks to make XML readable. Minify removes all unnecessary whitespace to produce the most compact XML possible, which is ideal for production use to reduce file size.
The Validate mode checks if your XML is well-formed (correct syntax, balanced tags, proper attribute quotes). It does not validate against XML Schema (XSD) or DTD. For schema validation, you would need a dedicated XML validator with schema support.
The Sort Attributes option alphabetically sorts all attributes within each XML element. This is useful for creating consistent, diff-friendly XML outputs, especially when comparing versions of configuration files or API responses.
The statistics panel displays: total elements, attributes, text nodes, comments, and the maximum nesting depth of your XML structure.
Yes, simply click the Download button and the result will be saved as a .xml file. You can also use the Copy button to copy the result to your clipboard.
Yes, the tool can handle XML files up to several megabytes. However, extremely large files (10MB+) may take longer to process depending on your device's performance. All processing remains client-side.
