It handles nested objects, arrays, and null values automatically."},{"question":"How do I use JSON to Python Dataclass?","answer":"Paste your JSON in the left panel. Choose between @dataclass or TypedDict style. The tool generates typed Python classes in the right panel. Copy and use them directly in your project."},{"question":"Does JSON to Python store my data?","answer":"No. All conversion happens entirely in your browser. Your JSON data never leaves your device — nothing is sent to any server."},{"question":"What is the difference between dataclass and TypedDict?","answer":"A dataclass creates a full class with __init__, __repr__, and __eq__. A TypedDict is a dictionary type hint — it only provides type checking without runtime behavior. Use dataclass for data objects, TypedDict for dictionary-shaped data."},{"question":"Does JSON to Python handle nested objects?","answer":"Yes. Nested JSON objects become separate Python classes. Arrays of objects create a shared class type. Null values are typed as Optional when that option is enabled."}],"howTo":[{"title":"Paste your JSON data","description":"Input a JSON object or array in the left panel. The tool parses the structure and infers Python types: strings become str, integers become int, decimals become float, booleans become bool, and null becomes Optional[Any]."},{"title":"Choose class style","description":"Select @dataclass for full class instances with __init__ and __repr__, or TypedDict for lightweight dictionary type hints. Toggle Optional for null handling."},{"title":"Review generated Python classes","description":"The right panel shows Python class definitions with proper type hints and imports. Nested objects become separate classes. Arrays of objects share a common class type."},{"title":"Copy and use in your project","description":"Click Copy to copy the generated Python definitions including imports. Paste them into your Python source file.
