XML Formatter
Format and beautify your XML code with proper indentation and structure
What is an Online XML Formatter?
An XML formatter, also known as an XML beautifier or XML pretty printer, is a specialized tool designed to transform poorly formatted or minified XML code into a clean, readable format. Our free online XML formatter automatically adds proper indentation, line breaks, and spacing to make your XML documents easier to read, debug, and maintain.
XML (eXtensible Markup Language) is a markup language that defines rules for encoding documents in a format that is both human-readable and machine-readable. However, XML files often become compressed, minified, or poorly formatted, making them difficult to work with. This is where an XML formatter becomes invaluable.
What Does Our XML Formatter Do?
Our XML formatter tool provides several key functionalities:
- Automatic Formatting: Instantly transforms unformatted XML into properly structured code with consistent indentation and line breaks.
- Real-time Processing: Format your XML code instantly without any delays or processing time.
- Preserve Content Integrity: The tool only modifies formatting while preserving all your original XML content, attributes, and structure.
- Error Detection: Identifies basic XML syntax errors and provides helpful error messages when invalid XML is detected.
- Statistics Display: Shows useful metrics including line count, character count, and element count after formatting.
Cross-platform Compatibility: Works seamlessly across all modern web browsers and devices without requiring any downloads or installations.
