Example: Null Values

// Input JSON:
{
  "name": "Alice",
  "middleName": null,

  <age>30</age>
</root>

// Or with xsi:nil attribute:
<root xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
  <name>Alice</name>
  <middleName xsi:nil="true"/>
  <age>30</age>
</root>

Example: JSON Properties as XML Attributes

    "name": "Widget",
    "price": 9.99,
    "currency": "USD"

</root>

Example: With XML Namespace

// Input JSON:
{
  "order": {
    "id": "ORD-001",
    "customer": "Alice",
    "total": 45.00
  }
}

// Output XML (with namespace):
<?xml version="1.0" encoding="UTF-8"?>
<root xmlns="https://example.com/orders/v1"
      xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
  <order>
    <id>ORD-001</id>
    <customer>Alice</customer>
    <total>45.00</total>
  </order>
</root>

    "includeProfile": true
  }
}

// Output XML (for SOAP body):
<GetUserRequest>
  <userId>42</userId>
  <includeProfile>true</includeProfile>
</GetUserRequest>

JSON to XML Type Mapping

JSON Type     XML Representation
──────────────────────────────────────────────────
string        Text content: <name>Alice</name>
number        Text content: <age>30</age>
boolean       Text content: <active>true</active>
null          Empty element: <field/> or xsi:nil="true"
object        Nested elements
array         Repeated elements with parent name

Paste your JSON to convert it to well-formed XML. Configure namespace declarations, attribute mapping, and null handling to match the requirements of your target XML-based system.

// Input JSON:
{
  "name": "Alice Smith",
  "age": 30,
  "email": "alice@example.com",
  "active": true
}

// Output XML:
<?xml version="1.0" encoding="UTF-8"?>
<root>
  <name>Alice Smith</name>
  <age>30</age>
  <email>alice@example.com</email>
  <active>true</active>
</root>
