XML Validator

Free Online XML Validator & Formatter

Need to check your XML files for syntax errors? Our free XML Validator instantly checks for well-formedness and potential issues. It also works as an XML Beautifier (Prettifier) to make ugly, minified XML code readable again.

What is XML?

XML (eXtensible Markup Language) is a markup language similar to HTML but designed to store and transport data. It's self-descriptive and valid XML must follow strict syntax rules, such as properly nested tags and a single root element.

Features

• Validate: Checks for syntax errors like unclosed tags or improper nesting.
• Beautify: Indents your code to make it human-readable.
• Minify: Removes whitespace to reduce file size for transport.
