FAQ

Does this tool upload my XML?

No. Parsing and formatting run locally in your browser; nothing is sent to a server.

Why does “Validate” fail even though the XML looks fine?

Common causes are unescaped &/< in text, mismatched tags, or invalid characters; the error box shows the parser message.

What does Minify do to my XML?

It removes whitespace-only text nodes between elements (and optionally comments) and outputs a compact single-line XML string.

Will formatting change my XML content?

It shouldn’t change element/attribute values, but indentation may affect XML where whitespace-only text nodes are meaningful (mixed content).

Why is the XML declaration missing after formatting?

Browsers often don’t re-emit <?xml ...?>; enable “Keep XML declaration” to preserve the original declaration line.

When should I use Escape vs Format?

Use Escape for plain text you want to embed inside XML; use Format for already-valid XML documents.

Can this tool remove XML comments?

Yes. Turn on “Remove comments” and then Format or Minify.
