Frequently Asked Questions

How are JSON arrays converted to XML?

Arrays become multiple sibling XML elements with the same tag name. Example: ['a', 'b'] → <item>a</item><item>b</item>.

Can I specify XML attributes in JSON?

Yes, use the @attr syntax in XML to JSON mode. For JSON to XML, attributes are not supported in this basic converter.

What about XML namespaces?

Basic namespace support is included. For complex XML Schema (XSD) transformations, server-side tools are recommended.

Is the conversion reversible?

Yes, you can convert JSON to XML and then back to JSON. Note that some structure may be lost (e.g., array vs single element ambiguity).

JSON object → XML element with its keys as child elements.
JSON array → repeated sibling elements with the same parent tag name.
JSON string / number → text content inside a tag.
JSON null → self-closing tag or empty element.
Key with @ prefix (in the XML→JSON direction) → XML attribute.
Root wrapper — XML requires exactly one root element; the converter wraps the JSON object in a configurable root tag (default: <root>).

Despite JSON's dominance in REST APIs, XML remains the standard in several domains:
