Pywin32保存为XLSM文件，而不是XLSX

Question

当我现在尝试保存一个XLSM文件，像这样：

from win32com.client import Dispatch 

# Open Excel workbook 
xl = Dispatch("Excel.Application") 
wb = xl.Workbooks.Add(r"C:\Users\ryan\Desktop\Book1.xlsm") 

# Make some changes 
# blah blah blah 

# Save the workbook in XLSM format with new name 

wb.SaveAs(r"C:\Users\ryan\Desktop\Book1 - XLSM.xlsm") 
xl.Quit() 

我提示以下错误......

Traceback (most recent call last): 
    File "<stdin>", line 1, in <module> 
    File "<COMObject Add>", line 7, in SaveAs 
pywintypes.com_error: (-2147352567, 'Exception occurred.', (0, 'Microsoft Excel' 
, 'This extension can not be used with the selected file type. Change the file e 
xtension in the File name text box or select a different file type by changing t 
he Save as type.', 'xlmain11.chm', 0, -2146827284), None) 

如何保存作为一种新的文件格式？

注意：当尝试将已经是XLSM的文件保存为XLSM时，会导致相同的错误。

该文件的格式由您在致电SaveAs时指定的参数FileFormat决定。由于您未指定值，因此选择了.xlsx的默认值。 documentation列出了可能的值。您需要使用xlOpenXMLWorkbookMacroEnabled。

的代码将是：

xlOpenXMLWorkbookMacroEnabled = 52 
.... 
wb.SaveAs(filename, FileFormat=xlOpenXMLWorkbookMacroEnabled)
