XML Formatter & Validator is an online application designed for developers to beautify, compress, and validate XML (eXtensible Markup Language) code. It can organize messy XML data into a clear, easy-to-read format.

• Prettify/Format: Convert single-line or unformatted XML code into a tree-like structure with proper hierarchy and indentation, greatly improving readability.
• Minify/Compact: Remove all unnecessary whitespace characters (spaces, newlines, tabs) from the XML code, effectively reducing file size without affecting the data structure.
• Syntax Highlighting & Validation: The tool checks whether your XML syntax is well-formed during formatting, including whether tags are properly closed and the hierarchy is clear, and can highlight basic syntax errors.
