Why convert XSD to JSON?
Converting XSD to .json JSON Schema is useful when migrating an XML-based API to a REST API: the XSD describes the existing data contract and the JSON Schema becomes its equivalent for validating JSON payloads or generating OpenAPI/Swagger documentation. Writing the JSON Schema by hand from large schemas is error-prone, so automated conversion saves time even if the output needs cleanup.
How to convert XSD to JSON
Altova MapForce APP
Create a new mapping with the .xsd as the source component and a JSON Schema as the target, draw or auto-map field connections, and run the mapping to generate the output JSON Schema.
xsdata OPEN-SOURCE
Install with pip install xsdata and run the conversion against your .xsd file; review the output for any unmapped constraints such as namespace declarations or element-ordering rules.

- This is a schema-to-schema conversion: the result is a JSON Schema rulebook, not a JSON data file ready for use in an application.
- XSD concepts such as namespaces, attribute-vs-element distinctions, and element ordering have no JSON Schema equivalent and will require manual additions after conversion.
- Do not upload XSD files containing sensitive internal data structures to public online tools.
