Frequently Asked Questions

Is the JSON to Python Generator free?
Yes, the JSON to Python Generator is completely free with no usage limits. Generate Python classes and type hints from JSON as often as you need without registration.
Is my JSON data private?
Yes, all code generation happens locally in your browser. Your JSON data never leaves your device, making it safe to generate code from API responses or configurations containing sensitive information.
What Python code does it generate?
The tool generates Python dataclasses or Pydantic models with proper type hints based on your JSON structure. It creates classes for nested objects and lists, with appropriate field types for strings, numbers, booleans, and null values.
Does it support Pydantic models?
Yes, the generator can output Pydantic BaseModel classes which provide runtime validation, serialization, and are commonly used in FastAPI and other modern Python frameworks. You can choose between dataclasses and Pydantic output.
Why generate Python code from JSON?
Generating Python classes from JSON ensures type safety when working with APIs, provides IDE autocomplete, enables data validation, and creates self-documenting code that matches your actual data structures.
