Why convert JSON to XML?
JSON is the standard for REST APIs and modern web apps. However, many enterprise systems, SOAP APIs, B2B data exchange standards (EDI, UBL, e-invoicing), and configuration files require XML. Converting JSON to XML bridges the gap between modern and legacy systems.
XML supports schema validation (XSD), namespaces, XSLT transformations, and digital signatures — features JSON lacks. In the enterprise world, XML remains the standard for SAP, Oracle, banking APIs (ISO 20022), and government systems.
The converter maps JSON objects to XML elements, arrays to repeating elements, and primitive types to text values. It generates well-formed, indented XML with a proper <?xml version="1.0"?> declaration.
All processing happens locally in your browser — nothing is sent to any server. No registration, no limits, no tracking.

How does JSON to XML conversion work?
JSON and XML are both structured data formats, but they use fundamentally different syntax. JSON uses curly braces and key-value pairs, while XML uses opening and closing tags to define elements. The converter maps each JSON property to an XML element, preserving the hierarchical structure.
JSON objects become XML elements, JSON arrays become repeated elements, and primitive values (strings, numbers, booleans) become text content within their parent tags. The converter generates well-formed XML with proper indentation and an XML declaration header.
XML is widely used in enterprise systems, SOAP web services, configuration files, and data interchange where strict schema validation is required. The conversion runs entirely in your browser — no data is sent to any server.
Tips for converting JSON to XML
A few tips to help you avoid common issues during conversion:
Root element
XML requires a single root element. If your JSON is an array, the converter wraps it in a root element. You can customize the root element name if needed.Array handling
JSON arrays are converted to repeated XML elements with the same tag name. The element name is derived from the parent key or uses a generic item tag.Special characters
Characters like <, >, &, and quotes are automatically escaped in the XML output using standard XML entities to ensure valid markup.Attributes vs elements
By default, all JSON properties become XML child elements. JSON does not have a native concept of XML attributes, so no attributes are generated.
JSON to XML mapping rules
The converter maps JSON structures to XML elements following these rules:
- Objects – each key becomes an XML element.
{"name": "John"}→<name>John</name> - Arrays – each item becomes a repeating element with the key name.
{"items": [1, 2]}→<items>1</items><items>2</items> - Primitives – strings, numbers, booleans become text content of their parent element.
- Null values – converted to empty elements or omitted.
The output includes a proper XML declaration and uses 2-space indentation for readability. Element names are derived directly from JSON keys.
