Json To Xml

The JSON to XML Converter transforms JSON objects and arrays into well-formed XML documents. Use it when integrating with legacy systems, SOAP APIs, or any service that expects XML input but your data source outputs JSON. The conversion preserves nested structures, arrays, and data types while producing valid, readable XML.

About the JSON to XML Converter

The JSON to XML Converter transforms JSON objects and arrays into well-formed XML documents. Use it when integrating with legacy systems, SOAP APIs, or any service that expects XML input but your data source outputs JSON. The conversion preserves nested structures, arrays, and data types while producing valid, readable XML.

How to use it

  1. Paste or type your JSON into the input field.
  2. Optionally set a root element name for the XML document.
  3. Click Convert to generate the XML output.
  4. Copy or download the resulting XML.

Formula & methodology

JSON object keys become XML element tag names. String/number values become element text content. JSON arrays become repeated elements with the same tag name. Nested objects become nested XML elements. Keys starting with @ become XML attributes. null values become empty elements.

Common use cases

  • Sending data to SOAP web services that require XML
  • Generating XML config files from JSON application settings
  • Integrating modern APIs with legacy XML-based systems
  • Creating XML sitemaps or RSS feeds from JSON data
  • Data migration: converting JSON records to XML format

Frequently asked questions

JSON arrays are represented as repeated XML elements with the same tag name. For example, {"items": ["a", "b"]} becomes <items>a</items><items>b</items> under a root element. Some converters wrap arrays in a parent element — the exact output depends on the implementation.
Most JSON can be converted, but some challenges exist: JSON keys that are not valid XML element names (starting with numbers, containing spaces) need sanitizing. JSON supports mixed types in arrays; XML is more rigid. Deeply nested JSON can produce verbose but valid XML. The converter handles these cases automatically.
