FAQ

XML formatting (pretty-printing) adds consistent indentation and line breaks to XML code, making the nested structure easier to read. Formatted XML is identical to the original in terms of data — only whitespace differs.

Yes. The formatter checks for well-formedness: properly nested tags, matched opening and closing elements, correct attribute syntax, and a single root element. Syntax errors are reported immediately.

No. All formatting happens entirely in your browser. Your XML code never leaves your device.

Formatting adds indentation and line breaks for readability. Minifying removes all unnecessary whitespace to reduce file size — useful in production environments where smaller file size matters.
