Frequently asked questions
1Does it validate XML?
The formatter parses the XML, so malformed input will produce an error. For full validation against an XSD schema, use the XML Validator tool which checks well-formedness and schema compliance with line numbers.
2Will it preserve my namespace declarations?
Yes. Namespace declarations (xmlns:prefix) are preserved exactly as they appear. The formatter only changes whitespace and indentation, not attribute order or content.
3Can it handle large XML files?
Yes. Parsing happens locally, so files up to several megabytes format without issue. For very large files, the output pane supports scrolling and copy-to-clipboard.
