Frequently asked questions
How does the tool select XML-to-JSON?
Trimmed input beginning with a less-than sign is parsed as XML; other input is parsed as JSON.
Are XML attributes preserved?
Yes. Attributes are retained as specially named JSON properties by the XML parser.
Will converting back reproduce identical XML?
Not always. Formatting, namespaces, mixed text and repeated nodes can change representation during parsing and rebuilding.
