.../site-packages/gspread_pandas/spread.py:401: FutureWarning: Downcasting behavior in replace is deprecated and will be removed in a future version. To retain the old behavior, explicitly call result.infer_objects(copy=False). To opt-in to the future behavior, set pd.set_option('future.no_silent_downcasting', True)
.replace("", np.nan)
