Frequently asked questions
How does JSON to Scala Case Classes infer types?+
It walks your JSON sample and maps each value to the closest static type — numbers, strings, booleans, arrays and nested objects each become the idiomatic type for the target language. Provide a complete example for the most accurate result.
Will the generated code compile as-is?+
It's designed to drop straight in, but you should review naming and nullability. JSON can't express every nuance (e.g. unions or optionals), so treat the output as a strong first draft you can refine.
