XML Formatter & Validator

XML (eXtensible Markup Language) is a markup language used to store and transport structured data. It is both human-readable and machine-readable, commonly used in web services, configuration files, and data interchange between systems.

XML formatting (beautifying) takes compact or poorly indented XML and re-indents it with consistent spacing and line breaks based on the nesting level of each element. This makes the document structure easier to read and debug.

XML minification removes all unnecessary whitespace, line breaks, and indentation between XML tags. This reduces file size for faster network transfers while preserving the exact same data and structure.

This tool uses the browser's built-in DOMParser to validate XML. It checks for well-formedness issues such as mismatched tags, missing closing tags, invalid characters, and improper nesting. Errors are displayed with details to help you fix them.

Two spaces is common in web development, four spaces is popular in enterprise/Java ecosystems, and tabs are preferred by some developers for flexibility. Choose what matches your project's conventions.
