XML Formatter

The XML Formatter parses and re-serializes XML documents into cleanly indented, human-readable format. Paste any XML string—minified, single-line, or inconsistently formatted—and click Format to get a structured version with consistent indentation. The tool uses the browser's native DOMParser for validation. If the XML is malformed, an error message is shown immediately so you can identify and fix the problem before moving on. Valid XML gets serialized with proper nesting, attribute quoting, and self-closing tags for empty elements. Choose between 2-space, 4-space, or tab indentation to match your team's coding standards. One-click copy to clipboard makes it easy to paste the result into your editor or codebase.
