Question 1

How does JSON structure map to XML?

Accepted Answer

JSON objects become XML elements with child elements for each key. Arrays become repeated elements with the same tag name. Primitive values become element text content. A root <root> element wraps the output when JSON doesn't have a single top-level object key.

Question 2

How are JSON keys with special characters handled?

Accepted Answer

XML element names cannot contain spaces, most punctuation, or start with numbers. This tool replaces invalid characters with underscores. For example, a JSON key 'my-key' becomes <my_key> in XML.

Question 3

Can I convert XML back to JSON?

Accepted Answer

Yes — click the Swap button to convert XML back to JSON. The xml-to-json direction parses the XML tree and creates a JSON object where each element becomes a key. Repeated sibling elements with the same tag become JSON arrays.

Question 4

Are JSON null values supported?

Accepted Answer

Yes. JSON null values become self-closing empty elements: <key/>. When converting back, empty elements become empty strings, not null, since XML has no null concept.

Question 5

What XML encoding is used?

Accepted Answer

Output includes the XML declaration . Special characters in text content (<, >, &) are escaped as XML entities (<, >, &) per the XML specification.

Question 6

How do I convert JSON to XML?

Accepted Answer

Paste your JSON object above and click Convert. The tool wraps JSON keys as XML elements and values as text content. Arrays become repeated elements. The root element wraps the entire structure. XML output is valid and downloadable. For the reverse, use DevDecode's XML to JSON Converter. For XML validation, use the XML Validator.

Question 7

When would I convert JSON to XML?

Accepted Answer

JSON to XML conversion is needed when integrating with legacy SOAP web services, generating RSS or Atom feeds, working with XML-native systems (XSLT, XPath), or communicating with enterprise systems that require XML. Most modern REST APIs use JSON. Use DevDecode's XML Formatter to clean and validate the converted XML output.
