About this tool

JSON and XML are both general-purpose data formats for representing structured data, but they have different design philosophies. JSON is minimal: it has six types (object, array, string, number, boolean, null) and a clear, unambiguous syntax. XML is a meta-language: it defines a grammar for creating custom markup languages, with support for attributes, mixed content (text interspersed with elements), namespaces, processing instructions, and document type definitions.

Converting between JSON and XML requires choosing a mapping strategy because the two formats have different expressive capabilities. In the most common approach, JSON objects become XML elements (where keys become child element names), JSON arrays become repeated sibling elements with the same tag, and primitive values become text content. This mapping loses XML-specific features: there is no direct equivalent in JSON for XML attributes, mixed content, or namespaces.

REST APIs commonly use JSON for its simplicity and natural fit with JavaScript. XML remains dominant in enterprise and legacy contexts: SOAP web services, financial data formats (FIX, SWIFT), configuration files for Java and .NET frameworks, Android manifests, Maven build files, Microsoft Office file formats (OOXML), and SVG all use XML. Converting between the two formats is a common integration task when connecting modern services with established enterprise systems.
