Frequently Asked Questions
What happens if my XML is invalid?
The tool shows a clear error message telling you the XML could not be parsed, instead of crashing or producing broken output.
Does formatting change my XML data?
No. It only changes whitespace and indentation. Element names, attributes and text stay exactly the same.
Can it format very large XML?
Yes for typical files. Extremely large documents may be slow in the browser — split them if needed.
Is my XML uploaded anywhere?
No. Formatting runs entirely in your browser.
