Generate Java models from JSON samples
The generator infers JSON primitives and nested structures to create a practical model skeleton. Use it to reduce repetitive setup, then review names and application-specific types before production use.
CODE GENERATORS
Open in Workspace →JSON → Java
Generate Java class structures from JSON while keeping nested objects and arrays explicit and readable.
OutputReady
Useful for everyday developer work
- Create Java models from REST response examples.
- Generate nested classes from object hierarchies.
- Start from a selected JSONPath when only one branch matters.
Use this tool in three steps
- Paste your data.
- Choose any available options and run the tool.
- Review, copy or download the result.

Frequently asked questions
Does the generator preserve nested structure?
Yes. Nested objects and arrays are represented recursively when their shape can be inferred.
Is generated Java production-ready automatically?
It is a starting point. Review naming, framework annotations, nullability and domain rules before production use.
Do I need an account?
No. Public deterministic tools work without signing in.
