JSON2dataclass is a tool to generate Python dataclass definitions from a JSON string easily in your browser.

Blog post on how to incorporate dataclasses in reading JSON API responses here

Heavily inspired by json-to-go

Example conversion:

From the Star Wars API

{
    "name": "Yavin IV",
    "rotation_period": "24",
    "orbital_period": "4818",
    "diameter": "10200",
    "climate": "temperate, tropical",
    "gravity": "1 standard",
    "terrain": "jungle, rainforests",
    "surface_water": "8",
    "population": "1000",
    "residents": [],
    "films": [
        "https://swapi.co/api/films/1/"
    ],
    "created": "2014-12-10T11:37:19.144000Z",
    "edited": "2014-12-20T20:58:18.421000Z",
    "url": "https://swapi.co/api/planets/3/"
}

turns into:

@dataclass

    name: str
    rotation_period: str
    orbital_period: str
    diameter: str
    climate: str
    gravity: str

    films: List[str]
