Convert JSON to Python dataclasses or TypedDict online. Generate typed Python code with proper type hints. Free, fast, and private.
About JSON to Python Conversion
Python's dataclasses and TypedDict provide structured ways to define typed data models. When consuming JSON APIs in Python, having properly typed classes improves code quality and IDE support. This tool analyzes your JSON and generates Python dataclasses with type hints or TypedDict definitions. It maps types correctly (str, int, float, bool, Optional, List), converts field names to snake_case, and creates separate classes for nested objects. The generated code includes proper imports from dataclasses and typing modules. All processing happens in your browser.
