As of Saturday, July 9th, I kept getting an error that "wb is not defined" when I called load_workbook.
We found that in line 46 (in function parse), self.wb is missing and it's just wb.excel_base_date ...
For some reason, the environment I was running the code on didn't catch this until Saturday because before then, everything worked fine. Anyway, when inserting self.wb... The code now runs properly.
