JSON to Python
Convert JSON data to Python dict, dataclass, or TypedDict syntax.
About this tool
JSON to Python is a conversion tool designed for developers who work with data interchange between JavaScript ecosystems and Python applications. JSON (JavaScript Object Notation) is widely used in APIs, configuration files, and web services, but Python developers often need to transform this data into native Python structures like dictionaries, dataclasses, or TypedDict for type safety and IDE autocomplete support.
Using this tool is straightforward: paste your JSON data into the input field, choose your desired output format (dict, dataclass, or TypedDict), and click convert. The tool instantly generates Python code you can copy and use directly in your projects. It handles nested objects, arrays, null values, and various data types automatically, saving you from manual rewriting and reducing syntax errors.
This tool is especially valuable when consuming REST APIs, importing configuration data, or migrating datasets from JavaScript to Python. The dataclass and TypedDict options add type annotations that improve code quality, enable better IDE support, and make refactoring safer. Whether you're building backend services, data pipelines, or integration layers, having instant Python syntax from JSON saves development time and reduces debugging headaches.

Code Implementation
import json
json_str = '{"name": "Alice", "age": 30, "active": true}'
data = json.loads(json_str)
print(data) # {'name': 'Alice', 'age': 30, 'active': True}
print(data["name"]) # Alice
# Using dataclass
from dataclasses import dataclass
from typing import Optional
@dataclass
class Person:
name: str
age: int
active: bool
person = Person(**data)
print(person.name) # Alice
# Using TypedDict
from typing import TypedDict
class PersonDict(TypedDict):
name: str
age: int
active: bool
typed: PersonDict = data
print(typed["age"]) # 30Comments & Feedback
