@dataclass
class Profile:
    country: str
    timezone: None

@dataclass
class ProjectsItem:
    name: str

    email: str
    is_active: bool

Generation notes

  • • Nested objects become separate dataclasses.
  • • Arrays receive Python list type hints.
  • • Null values can be represented with nullable types.
  • • Python reserved keywords are converted into safe field names.
  • • Mixed object arrays are merged using their available fields.

Generate Python dataclasses from your JSON in three steps.

1

Paste JSON

2

Configure

Choose your root class name and nullable type preference.

3

Generate

Copy your Python code or download the generated file.
