Can json to python dataclass converter handle lists of objects?

Yes. JSON arrays of objects become list fields with nested dataclass types inferred from the first element shape.

Does output use typing.Optional for null?

Null JSON values map to optional-friendly types in generated hints so you can refine with Optional where needed.

Yes. Use the language dropdown to regenerate models for other targets without re-pasting.

Python services and data scripts often need typed models matching a JSON webhook or REST response before writing pydantic or requests code.

Paste JSON, choose Python, and receive dataclasses with inferred field types and nested classes named from object keys.

Backend engineers prototyping FastAPI or Django integrations use this converter without installing CLI json2python tools.
