What is JSON to Python Converter?
This tool automatically converts JSON objects into Python class definitions. It supports three popular Python patterns: Dataclass, TypedDict, and Pydantic BaseModel. Perfect for developers who need to quickly generate Python type definitions from JSON data structures.
Features
- Automatically detects JSON data types (string, number, boolean, array, object)
- Generates three Python patterns: Dataclass, TypedDict, and Pydantic BaseModel
- Converts camelCase keys to snake_case for Python naming conventions
- Handles nested objects and arrays with proper type annotations
- Supports Optional types for nullable fields
- One-click copy functionality for generated Python code
Supported Conversion Modes
- Dataclass: Uses Python's @dataclass decorator for immutable data structures
- TypedDict: Uses typing.TypedDict for dictionary-based type hints
- Pydantic BaseModel: Uses Pydantic for data validation and serialization
