What is XML Formatting?
XML formatting, also known as pretty-printing, adds proper indentation and line breaks to XML documents to make them human-readable. Well-formatted XML is easier to read, debug, and maintain, especially for complex documents with deep nesting.
How to Use
- Paste your XML into the input field
- Click "Format XML" to beautify your document
- Copy the formatted result
Example
Input (minified XML):
<root><user id="1"><name>John</name><email>john@example.com</email></user></root>Output (formatted XML):
<root>
<user id="1">
<name>John</name>
<email>john@example.com</email>
</user>
</root>Technical Notes
This tool uses the browser's native DOMParser for XML validation and parsing. It preserves all XML features including attributes, comments, and CDATA sections. For very large XML files (>100KB), the tool automatically uses a Web Worker to prevent browser freezing.
Privacy Notice
All XML formatting happens entirely in your browser. Your XML documents are never transmitted to any server, ensuring complete privacy for sensitive configuration files and data.
Frequently Asked Questions
Does this tool validate XML?
Yes, the formatter uses the browser's DOMParser which validates XML syntax. If your XML is invalid, you'll see a clear error message indicating what's wrong. Common issues include unclosed tags, mismatched tags, or invalid characters.
Will formatting change my XML data?
No, formatting only adds whitespace (spaces and line breaks) for readability. The actual content, structure, attributes, and data remain unchanged. The formatted XML is functionally identical to the input.
Can I format XML with namespaces?
Yes, this tool fully supports XML namespaces. Namespace prefixes and declarations are preserved in the formatted output.
What about CDATA sections and comments?
CDATA sections and XML comments are preserved during formatting. Comments maintain their content, and CDATA sections keep their raw text without escaping.
Is my XML sent to a server?
No, all XML formatting happens in your browser. Your documents never leave your device, ensuring complete privacy for configuration files, data exports, and sensitive XML content.
