# datason

> datason is a zero-dependency Python library that serializes any Python object to JSON and back. It is a drop-in replacement for `json.dumps`/`json.loads` that handles datetime, UUID, Decimal, Path, NumPy arrays, Pandas DataFrames, PyTorch tensors, TensorFlow tensors, and scikit-learn models out of the box. Install with `pip install datason`. Requires Python 3.10+.

datason's API is intentionally minimal: 5 functions that mirror the stdlib `json` module. Every type beyond JSON primitives is handled by a plugin-based registry that serializes objects to `{"__datason_type__": "typename", "__datason_value__": <data>}` metadata dicts, enabling perfect round-trip fidelity.
