Why Convert JSON to XML?

While modern APIs use JSON, many enterprise systems, legacy SOAP services, and data warehouses still require XML format. Converting JSON to XML is common when integrating modern microservices with older enterprise infrastructure.

JSON to XML Conversion Rules

JSON objects become XML elements: {"name":"Alice"} → <name>Alice</name>
JSON arrays become repeated elements with the parent key name
Nested objects become nested elements
Numeric/boolean values are converted to element text content
JSON null → self-closing empty element: <field/>

Common XML Output Use Cases

SOAP API integration: REST JSON → SOAP XML payload
Legacy enterprise databases (IBM DB2, SAP, Oracle) requiring XML feeds
RSS/Atom feed generation from JSON data
Android layout configuration from JSON design specs
Maven/Ant build file generation from JSON configurations

json

// JSON Input
{
  "person": {
    "name": "Alice",
    "age": 28,
    "roles": ["admin", "editor"]
  }
}

// XML Output
<?xml version="1.0" encoding="UTF-8"?>
<root>
  <person>
    <name>Alice</name>
    <age>28</age>
    <roles>admin</roles>
    <roles>editor</roles>
  </person>
</root>

Frequently Asked Questions

Does the JSON to XML converter handle arrays?

Yes. JSON arrays are converted to repeated XML elements with the parent key name. Each array item becomes a separate element.

Can I convert XML back to JSON?

Yes. Switch the direction selector to XML → JSON and paste your XML: element names become object keys, text is coerced to numbers and booleans where it looks like one, and repeated sibling elements collapse into an array. Attributes are not carried across.

Does the XML output include an XML declaration?

Yes. The output includes the standard <?xml version="1.0" encoding="UTF-8"?> declaration at the top.
