About XML Formatter

Format, compress, or validate XML with precision. Ideal for configs, APIs, data interchange, and debugging.

  • Format: Beautify with configurable indentation.
  • Compress: Remove whitespace for minimal output.
  • Validate: Check for basic well-formedness and tag mismatch.
  • Line Numbers & Highlight: Navigate and debug large XML easily.
  • Keyboard Shortcuts: Ctrl+Enter to copy, Ctrl+K to clear.

⚠️ This tool uses a lightweight parser. For DTD, namespaces, or complex validation, use dedicated XML IDEs.
