Comment utiliser : JSON to Python
- Paste a JSON sample in the input — Python is already selected.
- Set the root type name and options such as optional fields and date detection.
- Copy the generated Python code into your project.
JSON to Python dataclasses
Each JSON object becomes a @dataclass with type hints — str, int, float, bool, list[...] and nested classes. Optional fields become Optional[...] = None, and keys that aren’t valid Python names are converted to snake_case.
Loading the JSON
json.loads() returns plain dicts; build the dataclasses from them, or paste the same structure into Pydantic models (Model.model_validate_json(data)) when you want validation and automatic conversion of nested objects.
Private by design
The conversion runs entirely in your browser — API responses with customer or internal data are never uploaded.
