I am trying to learn
Python (day 2) and am hoping to practice with
Excel books first as this is where I am comfortable/fluent.
Right off the bat I am having an error that I don't quit understand when running the below code:
import openpyxl wb = openpyxl.load_workbook("/Users/Scott/Desktop/Workbook1.xlsx") print(wb.sheetnames)
This does print my sheet names as requested, but it is followed by:
/Users/Scott/PycharmProjects/Excel/venv/lib/python3.7/site-packages/openpyxl/worksheet/_reader.py:293: UserWarning: Unknown extension is not supported and will be removed warn(msg)
I have found other questions that point to slicers/conditional formatting etc, but that does not apply here. This is a book I just made and only added 3 sheets before saving. It has no data, no formatting, and the extension is valid. I have no add-ons installed on my excel either.
Any idea why why I am getting this error? How do I resolve?
