I am trying to password protect an entire Excel file (same functionality as File > Protect Workbook > Encrypt with Password) using Python.
I have come across openpyxl and the protection features it offers (https://openpyxl.readthedocs.io/en/stable/protection.html) seems to fulfill this need. I have the following code:
from openpyxl import Workbook
from openpyxl import load_workbook
test_spreadsheet = "test.xlsx"
wb = load_workbook(test_spreadsheet)
wb.security.workbookPassword = "password"
However, I am getting the following error:
AttributeError: 'NoneType' object has no attribute 'workbookPassword'
Does anyone …
