Paste or type your content directly into the provided text area.
Yes. After the initial page load, GraphQL Schema to JSON Schema runs entirely on your device with no internet connection needed. All processing is done locally.
JSON Schema is used by OpenAPI, form validators, and REST API tools. Converting GraphQL schemas enables code generation, validation, and documentation in ecosystems that don't natively support GraphQL.
Scalar types, object types, interfaces, unions, enums, input types, non-null markers, and list types are mapped to their JSON Schema equivalents with appropriate type constraints.
Yes. Nested object types, recursive references, and deeply nested structures are correctly converted with JSON Schema's $ref mechanism for complex types.
Yes. The generated JSON Schema can be embedded in OpenAPI definitions, used with schema validators, or fed into code generators that consume JSON Schema.
No. All conversion happens locally in your browser. No schema data is sent to any server.
