FAQ

How do I format XML for Notepad++ using this tool?

Copy XML from Notepad++ into the input, click Format, then copy the output back into Notepad++.

Does this validate XML or only pretty print it?

It validates by parsing the XML and shows an error when the XML is not well-formed; otherwise it reports “Valid XML”.

Will minify change the meaning of my XML?

Minify removes whitespace between tags but keeps text content inside elements; always review if your XML relies on mixed-content whitespace.

Can I keep the XML declaration like <?xml version="1.0"?>

Yes—enable Keep XML declaration; it’s preserved only if it exists in your input.

Does it keep comments (<!-- like this -->)?

Yes by default; uncheck Keep comments to remove them from the output.

Why does Notepad++ show a different indentation than this tool?

Different formatters apply different rules; adjust indent size, tabs, and “Inline text-only elements” to match your preferred style.

Is my XML sent to a server?

No—formatting and validation run in your browser, and the tool does not make network requests.
