XML Formatter / Validator
Format, beautify and validate XML with customizable indentation.
How to Use the XML Formatter
Paste your XML into the input box, then click "Format" to beautify it with proper indentation, "Minify" to compress it into a single line, or "Validate" to check if it is well-formed XML.
What This Tool Does
- Format / Beautify — adds indentation and line breaks for readability
- Minify — removes all unnecessary whitespace to reduce file size
- Validate — checks whether the XML is well-formed and shows any errors
- Custom Indentation — choose 2 spaces, 4 spaces, or tabs
The tool runs entirely in your browser using the built-in DOMParser API. No data is sent to any server.
Frequently Asked Questions
How do I validate XML?
Paste your XML and click the Validate button. If the XML is well-formed, you will see a green "Valid XML" message. Otherwise, an error message explains what went wrong.
What is the difference between Format and Minify?
Format adds indentation and line breaks so the XML is easy to read. Minify removes all unnecessary whitespace and line breaks to create the smallest possible output.
Can I change the indentation style?
Yes. Use the Indent dropdown to choose between 2 spaces, 4 spaces, or tab indentation before clicking Format.
Does my XML get uploaded?
No. All formatting and validation happens locally in your browser. Your data never leaves your device.
