FAQ

Is my XML uploaded to a server?
No. Formatting runs locally in your browser, so the XML does not leave your device.
What XML files are supported?
Standard XML, SVG, XSL, XSD, WSDL, and other common XML-based formats.
What if formatting fails?
Check that the XML is well-formed. The error message shows the specific line and column.
Can formatting preferences be saved?
Yes. Indent, comment, and attribute options are saved in localStorage for this browser.
What is the difference between format and minify?
Format beautifies indentation for readability. Minify removes all extra whitespace for the smallest file size.
