Yes, you can use [NumPy](https://numpy.org) to do so. Convert the column(s) to NumPy arrays via [`deephaven.numpy.to_numpy`](/core/pydoc/code/deephaven.numpy.html#deephaven.numpy.to_numpy), then with [json.JSONEncoder](https://docs.python.org/3/library/json.html). For more information on NumPy and JSON for this use case, see [here](https://pynative.com/python-serialize-numpy-ndarray-into-json/).
