Why can't I “save as” an Excel file from my Python code?

问题

I have an Python ExcelDocument class that provides basic convenience methods for reading/writing/formatting Excel files, and I'm getting a strange error in seemingly simple Python code. I have a save and saveAs method:

def save(self):
   ''' Save the file '''
   self.workbook.Save()

def saveAs(self, newFileName):
   ''' Save the file as a new file with a different name '''
   self.workbook.SaveAs(newFileName)

The save method works perfectly, but when I try to call the saveAs method - myExcelObject.saveAs("C:/test.xlsx") - I get the following error:

Traceback (most recent call last):
  File "C:\workspace\Utilities\src\util\excel.py", line 201, in <module>
    excel.saveAs("C:/test.xlx")
  File "C:\workspace\Utilities\src\util\excel.py", line 185, in saveAs
    self.workbook.SaveAs(newFileName)
  File "<COMObject Open>", line 7, in SaveAs

Can anyone explain what is happening?

回答1:

I've found (the hard way) that SaveAs doesn't support slash /.
Try saveAs("C:\\test.xlx") instead.
