win32com Trying to open a xlmb file with macros

[diegoctn]

Hi guys, I am now using the code below:
import xlrd
file_location='O:\xxx\xxxxxx\xxx.xlsm'
workbook = xlrd.open_workbook(file_location)
#sheet = workbook.sheet_by_index(2)
xl_sheet =workbook.sheet_by_name("B Data")

for rownum in range(xl_sheet.nrows):
print (xl_sheet.row_values(rownum))

It reads the data from an Excel file which uses a third part add in that update the data. The point is that I only see the original data but not the updated. Let's say that the Cell 1 Col A has 20 as value, this is what Python shows me. Now, if I see the file on the machine with the plug in installed the value is 22 but the code in Python still shows me 20. Any idea how can I set a process to see the data when it is changed and not only the original one?

Thanks
