Frequently Asked Questions
How does JSON to Python dataclass conversion work?
The tool analyzes your JSON structure and generates Python dataclasses with proper type hints using the dataclasses module. Nested objects become separate dataclass definitions.
What Python version is required for the generated code?
The generated dataclasses use the @dataclass decorator and type hints, requiring Python 3.7 or later. The Optional type from the typing module is used for nullable fields.
Does it handle nested objects and arrays?
Yes. Nested JSON objects become separate dataclass definitions, and arrays are typed as List[Type] using the appropriate element type.
Is my data safe?
Yes! All processing happens entirely in your browser. Your JSON data is never sent to any server. No data is collected, stored, or transmitted.
What Python types are generated from JSON values?
JSON strings map to str, numbers to int or float, booleans to bool, null to Optional[Any], arrays to List, and objects to named dataclass types.
