Frequently asked questions
Does this tool validate XML before formatting?
Yes. It checks XML syntax first and shows an error if tags or structure are invalid.
Can I minify XML as well?
Yes. Switch to Minify mode to remove unnecessary whitespace and output compact XML.
Will this work for large XML files?
It works well for typical browser-sized inputs. Very large documents may be slower depending on your device.
