How do I call an Excel macro from Python using xlwings?

Question

I've read the API docs for xlwings, and played around with Workbook and Sheet objects in the interpreter, but I can't figure out how to call a macro from Python.

How do I use xlwings to call an Excel macro from Python?

Answer 1

This is not implemented yet, but there's an open issue for it, see here. In the meantime, you can work around it like so (this is for Windows, but the Mac version works accordingly, see again in the issue):

from xlwings import Workbook
wb = Workbook(...)
wb.application.xl_app.Run("your_macro")

update: for more recent versions, you have to do:

from xlwings import Workbook, Application
wb = Workbook(...)
Application(wb).xl_app.Run("your_macro")

update 2: This functionality is now natively supported from >=v0.7.1. Let's assume, there is a VBA function YourMacro that sums up two numbers:

>>> import xlwings as xw
>>> wb = xw.Book(r'C:\path\to\mybook.xlsm')
>>> your_macro = wb.macro('YourMacro')
>>> your_macro(1, 2)
