About this tool
About this tool
XML Formatter indents and pretty-prints XML markup by parsing elements, attributes, and nesting depth locally in your browser. It improves readability while keeping content and entity references intact.
Format and validate XML documents with readable indentation. Use the full-width workspace to format content while reviewing syntax, encodings, protocol fields, and implementation details. The tool accepts plain text, provides focused options, and creates XML output that you can inspect, copy, download, or save as a local draft.

Key features
Key features
Well-formed output with proper nesting
Elements are indented to their depth. Closing tags are aligned with opening tags so the hierarchy is clear.
Attributes and text content preserved
Element attributes stay on their original tags. Text nodes, CDATA sections, and comments are not stripped or altered.
Copy and download formatted XML
Copy or download the tidy XML for configuration files, data feeds, or documentation.
Does not validate against a DTD or schema
The formatter restructures whitespace. It does not check element order, required attributes, or data type constraints.

Limitations and important notes
Limitations and important notes
- Formatting improves readability but does not guarantee semantic correctness.
- Large or deeply structured input depends on available browser memory and may process more slowly on mobile devices.
- The tool implements practical browser-based processing and may not reproduce every feature of specialist desktop software or every vendor-specific extension.
- Keep the original source and review generated output before production, security-sensitive, financial, legal, or safety-critical use.
