Question 1

What languages does the JSON to Code generator support?

Accepted Answer

The tool generates typed code in 8 languages: TypeScript interfaces, Python dataclasses, Java POJOs, Go structs with json tags, C# classes with properties, Kotlin data classes, Rust structs with serde, and Swift Codable structs.

Question 2

How does the tool infer types from JSON?

Accepted Answer

The generator analyzes each JSON value to determine its type. Strings become string types, integers become int/Int/i64, floats become float/Double/f64, booleans become bool/Boolean, null becomes the language's nullable type, and nested objects become named types.

Question 3

Can I customize the root type name?

Accepted Answer

Yes. Use the Root Type input field to change the name of the top-level generated type. Nested types are automatically named based on their JSON key names using PascalCase convention.

Question 4

How are nested objects and arrays handled?

Accepted Answer

Nested objects automatically generate their own named types (classes, structs, or interfaces depending on the language). Arrays of objects generate a separate type for the array element, with the type name derived from the singularized key name.
