问题描述

我正在尝试从我的Python代码调用一个VBA子代码,将指定文件夹中的所有excel文件从xls转换为xlsm格式。



我可以使用以下代码当我没有在VBA中使用一个变量,它的效果很好。



Python代码

  import os 
import win32com.client

xl = win32com.client.Dispatch(Excel.Application)
xl.Workbooks.Open(Filename =C:\Users\Name\Documents\PERSONAL.XLSB,ReadOnly = 1)
xl.Application.Run(PERSONAL.XLSB!Module1。 xlstoxlsmFinal
xl.Application.Quit()#如果您的excel脚本关闭,请注释
del xl

VBA代码

  Public Sub xlstoxlsmFinal()

'通过指定文件夹的所有子文件夹,并创建任何xls文档的xlsm(启用宏的版本)


Dim fso,oFolder,oSubfolder,oFile,queue作为集合

设置fso = CreateObject(Scripting.FileSystemObject)
设置队列=新集合
路径=C:\Users\Name\Documents\Monthly Reports\16.06报告\Agent Reports
queue.Add fso.GetFolder(Path)

尽管queue.Count> 0
设置oFolder = queue(1)
queue.Remove 1'dequeue
'...在这里插入任何文件夹处理代码
对于每个oSubfolder在oFolder.SubFolders
queue.Add oSubfolder'enqueue
下一个oSubfolder
对于每个oFile在oFolder.Files
如果右(oFile,4)<> xlsm和右(oFile,3)<> pdf然后
Workbooks.Open文件名:= oFile
ActiveWorkbook.SaveAs文件名:= oFile& m,FileFormat:= xlOpenXMLWorkbookMacroEnabled,CreateBackup:= False
ActiveWorkbook.Close
End If
Next oFile
Loop
pre>

但是,当我尝试将变量从python传递给VBA时,无法调用该函数。以下是我迄今为止所尝试的。



具有变量的Python代码:

  import os 
import win32com.client

Datev =16.06
xl = win32com.client.Dispatch( Excel.Application)
xl.Workbooks.Open(Filename =C:\Users\Name\Documents\PERSONAL.XLSB,ReadOnly = 1)
xl.Application.Run PERSONAL.XLSB!Module1.xlstoxlsmFinal(+ Datev +))
## xl.Application.Save()#如果要保存,则取消注释此行并更改删除,ReadOnly = 1部分从开放功能。
xl.Application.Quit()#注释如果你的excel脚本关闭
del xl

具有变量的VBA代码

  Public Sub xlstoxlsmFinal(Datev As String)

'遍历指定文件夹的所有子文件夹,并创建任何xls文档的xlsm(启用宏的版本)


Dim fso,oFolder,oSubfolder, oFile,queue As Collection

设置fso = CreateObject(Scripting.FileSystemObject)
设置队列=新集合
路径=C:\Users\Name\ Documents \Monthly Reports\& Datev& Reports\Agent Reports
queue.Add fso.GetFolder(Path)

尽管queue.Count> 0
设置oFolder = queue(1)
queue.Remove 1'dequeue
'...在这里插入任何文件夹处理代码
对于每个oSubfolder在oFolder.SubFolders
queue.Add oSubfolder'enqueue
下一个oSubfolder
对于每个oFile在oFolder.Files
如果右(oFile,4)<> xlsm和右(oFile,3)<> pdf然后
Workbooks.Open文件名:= oFile
ActiveWorkbook.SaveAs文件名:= oFile& m,FileFormat:= xlOpenXMLWorkbookMacroEnabled,CreateBackup:= False
ActiveWorkbook.Close
End If
Next oFile
Loop
pre>

当我在python中运行时,我收到错误消息:

  pywintypes.com_error:(-2147352567,异常发生,(0,u'Microsoft Excel',u无法运行宏PERSONAL.XLSB!Module1.xlstoxlsmFinal(16.06)。宏可能不可用在这个工作簿或所有宏可能被禁用。,u'xlmain11.chm',0,-2146827284),无)

有没有人知道如何成功地将Python变量传递给VBA子?



谢谢!

解决方案

Per Tim Williams建议我阅读了rondebruin.nl/win/s9/win001.htm的最后一节,并制定了python代码

  import os 
import win32com.client

Datev =16.06
xl = win32co m.client.Dispatch(Excel.Application)
xl.Workbooks.Open(Filename =C:\Users\Name\Documents\PERSONAL.XLSB,ReadOnly = 1)
xl.Application.Run(PERSONAL.XLSB!Module1.xlstoxlsmFinal,Datev)
xl.Application.Quit()#如果您的excel脚本关闭,请注释
del xl

物料差异正在更改:

  xl.Application.Run(PERSONAL.XLSB!Module1.xlstoxlsmFinal(+ Datev +))

To:

  xl.Application.Run(PERSONAL.XLSB!Module1.xlstoxlsmFinal Datev)

现在代码工作完美!


I am trying to call a VBA sub from my Python code to convert all excel files in a specified folder from the xls to xlsm format.

I can use the following code when I am not using a variable in the VBA and it works well.

Python Code:

import os
import win32com.client

xl=win32com.client.Dispatch("Excel.Application")
xl.Workbooks.Open(Filename="C:\Users\Name\Documents\PERSONAL.XLSB", ReadOnly=1)
xl.Application.Run("PERSONAL.XLSB!Module1.xlstoxlsmFinal"
xl.Application.Quit() # Comment this out if your excel script closes
del xl

VBA Code:

Public Sub xlstoxlsmFinal()

' goes through all the sub folders of a specified folder and created an xlsm(macro enabled version) of any xls documents


    Dim fso, oFolder, oSubfolder, oFile, queue As Collection

    Set fso = CreateObject("Scripting.FileSystemObject")
    Set queue = New Collection
    Path = "C:\Users\Name\Documents\Monthly Reports\16.06 Reports\Agent Reports"
    queue.Add fso.GetFolder(Path)

    Do While queue.Count > 0
        Set oFolder = queue(1)
        queue.Remove 1 'dequeue
        '...insert any folder processing code here...
        For Each oSubfolder In oFolder.SubFolders
            queue.Add oSubfolder 'enqueue
        Next oSubfolder
        For Each oFile In oFolder.Files
                If Right(oFile, 4) <> "xlsm" And Right(oFile, 3) <> "pdf" Then
                Workbooks.Open Filename:=oFile
                ActiveWorkbook.SaveAs Filename:=oFile & "m", FileFormat:=xlOpenXMLWorkbookMacroEnabled, CreateBackup:=False
                ActiveWorkbook.Close
    End If
        Next oFile
    Loop

However, I am unable to call the function when I try to pass a variable from python to VBA. Below is what I have tried so far.

Python code with variable:

import os
import win32com.client

Datev = """16.06 """
xl=win32com.client.Dispatch("Excel.Application")
xl.Workbooks.Open(Filename="C:\Users\Name\Documents\PERSONAL.XLSB", ReadOnly=1)
xl.Application.Run("PERSONAL.XLSB!Module1.xlstoxlsmFinal(" + Datev + ")")
##    xl.Application.Save() # if you want to save then uncomment this line and change delete the ", ReadOnly=1" part from the open function.
xl.Application.Quit() # Comment this out if your excel script closes
del xl

VBA code with Variable:

Public Sub xlstoxlsmFinal(Datev As String)

' goes through all the sub folders of a specified folder and created an xlsm(macro enabled version) of any xls documents


    Dim fso, oFolder, oSubfolder, oFile, queue As Collection

    Set fso = CreateObject("Scripting.FileSystemObject")
    Set queue = New Collection
    Path = "C:\Users\Name\Documents\Monthly Reports\" & Datev & "Reports\Agent Reports"
    queue.Add fso.GetFolder(Path)

    Do While queue.Count > 0
        Set oFolder = queue(1)
        queue.Remove 1 'dequeue
        '...insert any folder processing code here...
        For Each oSubfolder In oFolder.SubFolders
            queue.Add oSubfolder 'enqueue
        Next oSubfolder
        For Each oFile In oFolder.Files
                If Right(oFile, 4) <> "xlsm" And Right(oFile, 3) <> "pdf" Then
                Workbooks.Open Filename:=oFile
                ActiveWorkbook.SaveAs Filename:=oFile & "m", FileFormat:=xlOpenXMLWorkbookMacroEnabled, CreateBackup:=False
                ActiveWorkbook.Close
    End If
        Next oFile
    Loop

When I run this in python I get the error message:

pywintypes.com_error: (-2147352567, 'Exception occurred.', (0, u'Microsoft Excel', u"Cannot run the macro 'PERSONAL.XLSB!Module1.xlstoxlsmFinal(16.06 )'. The macro may not be available in this workbook or all macros may be disabled.", u'xlmain11.chm', 0, -2146827284), None)

Would anybody know how to succesfully pass a Python variable to a VBA sub?

Thanks!

解决方案

Per Tim Williams suggestion I read the last section of rondebruin.nl/win/s9/win001.htm and formulated the python code

    import os
    import win32com.client

    Datev = """16.06 """
    xl=win32com.client.Dispatch("Excel.Application")
    xl.Workbooks.Open(Filename="C:\Users\Name\Documents\PERSONAL.XLSB", ReadOnly=1)
    xl.Application.Run("PERSONAL.XLSB!Module1.xlstoxlsmFinal", Datev)
    xl.Application.Quit() # Comment this out if your excel script closes
    del xl

The material difference was changing the line:

xl.Application.Run("PERSONAL.XLSB!Module1.xlstoxlsmFinal(" + Datev + ")")

To:

xl.Application.Run("PERSONAL.XLSB!Module1.xlstoxlsmFinal", Datev)

Now the code works perfectly!
