The dataclass-wizard library provides a set of simple, yet elegant wizarding tools for interacting with the Python dataclasses module in Python 3.9+.

The primary use is as a fast serialization framework that enables dataclass instances to be converted to/from JSON; this works well in particular with a nested dataclass model.

The dataclass-wizard is pure Python code that relies entirely on stdlib, with the only added dependency being typing-extensions https://pypi.org/project/typing-extensions/ for Python 3.9 and below.
