          Input arguments:
          - inplace - If True, sets the object attribute. If False, returns the value.
          - overwrite - if True, performs conversion and replaces target field attribute even if the
            target attribute already has a value. If False, does not perform conversion in the aforementioned case.
            Set to True (do conversion) if inplace=False.
