Overwrite a hosted feature service using ArcGIS API for Python converts it to a hosted table when the source data is an Excel file.

Workaround

Use CSV input data instead of Excel. It is possible to convert Excel to CSV in Python using pandas.

import pandas as pd

data_xls = pd.read_excel(r"<PATH TO EXCEL FILE>", "<EXCEL SHEET NAME>", index_col=None)

data_xls.to_csv(r"<PATH TO OUTPUT>", encoding='utf-8')
