About this tool

Convert JSON to XML and back, with a reversible convention for arrays, attributes and mixed text content.

The JSON ↔ XML Converter is a bidirectional format translation tool that transforms JSON data into well-formed XML documents and vice versa, preserving structure, data types, and nesting relationships. It's essential for developers integrating systems that communicate in different data formats — REST APIs returning JSON consuming SOAP services expecting XML, or legacy XML databases feeding modern JSON-based frontends.

The converter intelligently maps between the two formats: JSON arrays become repeated XML elements, nested objects become child elements, and JSON values become text content or attributes depending on your configuration. You can control whether values are represented as XML attributes or child elements, how arrays are handled (repeated elements vs. wrapper elements), and the root element naming convention for the XML output.

For data migration projects, API integration work, and legacy system modernization, this tool eliminates the need for custom conversion scripts. All processing is client-side — your data, which may contain business records, configuration, or personal information, never leaves your browser.
