JSON to XML

Paste your JSON data into the input field and click the Convert to XML button. The tool will transform your JSON structure into equivalent XML format, creating elements and attributes that represent your data hierarchy.

JSON to XML conversion is useful when working with legacy systems, SOAP web services, enterprise applications, or any system that requires XML format. It's also helpful for data exchange between modern JSON-based systems and older XML-based infrastructure.

JSON arrays are typically converted into multiple XML elements with the same tag name, or wrapped in a container element. The tool intelligently handles arrays to create valid, well-structured XML output.

Yes, the tool handles deeply nested JSON structures, converting them into hierarchical XML elements. Parent-child relationships are preserved, and the resulting XML maintains the same data structure as your original JSON.

Yes, the tool generates valid, well-formed XML that conforms to XML specifications. The output includes proper opening and closing tags, correct nesting, and escaped special characters where necessary.

Special characters like <, >, &, and quotes are automatically escaped in the XML output according to XML standards. This ensures the generated XML is valid and the data is preserved exactly as it appears in your JSON.

JSON null values can be represented in XML several ways: as empty elements (<value/>), elements with xsi:nil="true" attribute (XML Schema standard), omitted elements, or elements with explicit null text. Empty strings in JSON typically become empty XML elements. The conversion strategy depends on the target system - SOAP services often prefer xsi:nil for nulls, while REST APIs might use empty elements. Some converters add type attributes to distinguish between null, empty string, and missing values for round-trip conversion accuracy.

JSON and XML have fundamental differences: JSON has native arrays ([]), while XML represents arrays as repeated elements; JSON has primitive types (string, number, boolean, null), while XML treats everything as text requiring type attributes; JSON uses key-value pairs, XML uses elements and attributes; JSON is more compact (less verbose), XML requires closing tags; JSON has one root type (object or array), XML requires a single root element. XML supports attributes, namespaces, and comments which JSON lacks. JSON is better for APIs and web applications, XML for documents and enterprise systems.

The JSON-to-XML mapping for attributes varies by converter. Common conventions: JSON properties starting with '@' become XML attributes ({"@id": "123", "name": "John"} → <item id="123"><name>John</name></item>), properties named '#text' or 'value' become element text content, or all properties become child elements by default. Some systems use JSON Schema or configuration to specify which properties should be attributes versus elements. For maximum compatibility, use elements for complex data and reserve attributes for metadata, IDs, and simple string values.
