dataclass-wizard (conda): The dataclass-wizard library provides a set of simple, yet elegant *wizarding* tools for interacting with the Python `dataclasses` module in Python 3.6+.  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.
