Load Excel add-in using win32com from Python

Question

I\'ve seen from various questions on here that if an instance of Excel is opened from Python using:

xl = win32com.client.gencache.EnsureDispatch(\'Excel.Applicat         


        

Answer 1

I had the same problem, but couldn't use xl.RegisterXLL('C:/path/addin.xla') from the accepted answer, because it only works with .XLL files, and I had a .XLA file.

Instead, I found that this worked:

xl = win32com.client.gencache.EnsureDispatch('Excel.Application')

# Need to load the addins before opening the workbook
addin_path = r'C:\path\addin.xla'
xl.Workbooks.Open(addin_path)
xl.AddIns.Add(addin_path).Installed = True

wb = xl.Workbooks.Open(r"C:\my_workbook.xlsm")
