Frequently Asked Questions
Is this XML Formatter free?
Yes, completely free. No signup, no limits.
Is my XML uploaded to a server?
No. All formatting happens in your browser using the built-in DOMParser. Your XML never leaves your device.
What is the difference between Format and Minify?
Format adds indentation and line breaks to make XML human-readable. Minify removes all unnecessary whitespace to make it as small as possible.
Does it validate XML?
Yes. Select 'Validate only' mode to check if your XML is well-formed. If there's an error, you'll see the exact message and location.
Does it support namespaces and CDATA?
Yes. XML namespaces, CDATA sections, comments, and processing instructions are all preserved.
Is this the same as HTML formatting?
No. XML is stricter than HTML — all tags must be closed, case matters, and attributes must be quoted. This tool is for XML only.
