Frequently asked questions

Why does it say my XML is invalid?

Common causes are a closing tag that does not match its opening tag, an unescaped & or < in text, an attribute without quotes, or more than one root element. The message gives the line and column to look at.

Are comments and CDATA kept?

Yes. Comments, CDATA sections, processing instructions and the DOCTYPE stay exactly as written. Tick “Remove comments” to drop comments.

Will formatting change my data?

Elements that contain text are kept on one line with their text untouched, so values and mixed content such as <p>Hello <b>there</b></p> do not change. Only whitespace between tags is adjusted.

Can it handle large files?

Yes. A 5 MB file formats in about a second because nothing is uploaded.

Is my data sent to a server?

No. Everything runs in your browser, so configs, API responses and code never leave your device.
