JSON to XML
Convert JSON data to XML format.
What is JSON to XML?
The JSON to XML converter transforms JSON data structures into valid, well-formed XML documents in seconds. Whether you're working with a simple JSON object or a deeply nested array, the tool maps JSON keys to XML elements and handles attributes, arrays, and primitive values automatically. This makes it an essential utility for developers who need to bridge the gap between modern JSON-based APIs and legacy XML-based systems.
XML remains widely used in enterprise environments, SOAP web services, configuration files, and data interchange formats like RSS and SVG. Having a reliable way to convert JSON to XML means you can quickly adapt data from a REST API response or a JavaScript application into a format that older systems, third-party integrations, or XML-based toolchains can consume — without writing custom serialization code.
How to Use
To use the tool, paste your JSON data into the input field. This can be a JSON object, an array of objects, or any valid JSON value. The tool parses the JSON and maps each key-value pair to a corresponding XML element. Object keys become element tag names, string and number values become element text content, and nested objects become child elements. Arrays are expanded into repeated sibling elements sharing the same tag name.
The output is a properly indented, well-formed XML document ready to copy or download. The root element is typically auto-generated (often named root) to ensure the XML document has a single top-level node, as required by the XML specification. You can then paste the result directly into an XML file, a SOAP request body, or any system that expects XML input.
A few edge cases to be aware of: JSON keys that contain spaces or special characters not valid in XML tag names will be sanitized or escaped automatically. JSON null values are typically represented as empty elements. Very large or deeply nested JSON structures will still convert correctly, but it's good practice to validate the output using an XML validator to confirm it meets your target schema requirements.
