Why use an XML Formatter?

XML (eXtensible Markup Language) is widely used for configuration files, data exchange, and document storage. Poorly formatted XML is hard to read and debug. Our XML formatter adds proper indentation, validates tag structure, and can also minify XML for production use, reducing file size and improving load times.

Key Features

  • Format and beautify XML with 2 or 4 space indentation
  • Validate XML structure with clear error messages
  • Minify XML for production deployment

How to use

  1. Paste your XML data in the input field
  2. Click Format to beautify or Minify to compress
  3. Copy the formatted or minified result

Technical Details

Our XML formatter parses the document structure, normalizes whitespace between tags, and applies consistent indentation. The validator checks for common errors like unclosed tags and mismatched tag pairs. Minification removes unnecessary whitespace while preserving text content within elements.

FAQ

Does this support XML namespaces?

Yes, our formatter handles XML with namespace declarations and prefixed elements correctly.

Can I format very large XML files?

The tool works with XML of any size that your browser can handle in memory. For very large files, performance may vary.
