JSON to Python Converter
Convert JSON to Python dict literals, dataclass definitions, TypedDict types, or Pydantic models. Handles nested objects, arrays, and proper Python syntax (True/False/None). Everything runs in your browser — your data stays private.
About JSON to Python Conversion
Python is the world's most popular programming language and works extensively with JSON data. Whether you're building REST APIs with Flask or FastAPI, processing data with pandas, or building machine learning pipelines, you constantly need to convert JSON payloads into Python structures. This tool automates that process with four different output formats.
The converter analyzes the structure and types of your JSON data and generates the appropriate Python code. JSON strings become str, numbers become int or float, booleans become bool, null becomes None (or Optional[type] in typed outputs), and nested objects become nested classes or dicts.
Features
- Dict Literal — Python dictionary with
True/False/Nonesyntax - Dataclass — Typed
@dataclassdefinitions with nested classes - TypedDict —
TypedDictclasses for static type checking with mypy - Pydantic —
BaseModelclasses for runtime validation with FastAPI - Handles deeply nested objects with separate named classes
- Arrays become
list[type]with proper element type inference - Nullable fields use
Optional[type]from thetypingmodule - Smart number detection: integers use
int, decimals usefloat - Syntax-highlighted Python output with color-coded keywords and types
- 100% client-side — your data never leaves your browser
