I’m using the Excel.Application COM object from a Python program to open a CSV file and save it as an Excel workbook. If the target file already exists, then I am prompted with this message: “A file named ‘…’ already exists in this location. Do you want to replace it?” That message comes up despite the fact that I have set the XlSaveConflictResolution value to xlLocalSessionChanges, which is supposed to automatically overwrite the changes without prompting — or so I thought.
I’m using Microsoft Office Excel 2007 (12.0.6535.5002) SP2 MSO and ActivePython 126.96.36.199. I have tried all three of the XlSaveConflictResolution values using both constants and integers. I have not tried different versions of Excel.
Here’s a code snippet:
import win32com.client xl = win32com.client.gencache.EnsureDispatch("Excel.Application") wb = xl.Workbooks.Open(r"C:\somefile.csv") wb.SaveAs(r"C:\somefile.xls", win32com.client.constants.xlWorkbookNormal, \ None, None, False, False, win32com.client.constants.xlNoChange, \ win32com.client.constants.xlLocalSessionChanges)
And here’s the spec from Microsoft about the SaveAs method for an Excel workbook object: http://msdn.microsoft.com/en-us/library/microsoft.office.tools.excel.workbook.saveas(VS.80).aspx
Could this be a new “feature” in Excel 2007, or did I just do something wrong?
Before saving the file set
False to suppress the warning dialog:
xl.DisplayAlerts = False
After the file is saved it is usually a good idea to set
DisplayAlerts back to
xl.DisplayAlerts = True
