Way to run Excel macros from command line or batch

Question

I have an Excel VBA macro which I need to run when accessing the file from a batch file, but not every time I open it (hence not using the open file event). Is there a way to run the macro from the command line or batch file? I'm not familiar with such a command.

Assume a Windows NT environment.

Answer 1

You can launch Excel, open the workbook and run the macro from a VBScript file.

Copy the code below into Notepad.

Update the 'MyWorkbook.xls' and 'MyMacro' parameters.

Save it with a vbs extension and run it.

Option Explicit

On Error Resume Next

ExcelMacroExample

Sub ExcelMacroExample() 

  Dim xlApp 
  Dim xlBook 

  Set xlApp = CreateObject("Excel.Application") 
  Set xlBook = xlApp.Workbooks.Open("C:\MyWorkbook.xls", 0, True) 
  xlApp.Run "MyMacro"
  xlApp.Quit 

  Set xlBook = Nothing 
  Set xlApp = Nothing 

End Sub 

The key line that runs the macro is:

xlApp.Run "MyMacro"

If you're more comfortable working inside Excel/VBA, use the open event and test the environment: either have a signal file, a registry entry or an environment variable that controls what the open event does.

You can create the file/setting outside and test inside (use GetEnviromentVariable for env-vars) and test easily. I've written VBScript but the similarities to VBA cause me more angst than ease..

As I understand the problem, you want to use a spreadsheet normally most/some of the time yet have it run in batch and do something extra/different. You can open the sheet from the excel.exe command line but you can't control what it does unless it knows where it is. Using an environment variable is relatively simple and makes testing the spreadsheet easy.

To clarify, use the function below to examine the environment. In a module declare:

Private Declare Function GetEnvVar Lib "kernel32" Alias "GetEnvironmentVariableA" _
    (ByVal lpName As String, ByVal lpBuffer As String, ByVal nSize As Long) As Long

Function GetEnvironmentVariable(var As String) As String
Dim numChars As Long

    GetEnvironmentVariable = String(255, " ")

    numChars = GetEnvVar(var, GetEnvironmentVariable, 255)

End Function

In the Workbook open event (as others):

Private Sub Workbook_Open()
    If GetEnvironmentVariable("InBatch") = "TRUE" Then
        Debug.Print "Batch"
    Else
        Debug.Print "Normal"
    End If
End Sub

Add in active code as applicable. In the batch file, use

set InBatch=TRUE

Answer 3

The simplest way to do it is to:

1) Start Excel from your batch file to open the workbook containing your macro:

EXCEL.EXE /e "c:\YourWorkbook.xls"

2) Call your macro from the workbook's Workbook_Open event, such as:

Private Sub Workbook_Open()
    Call MyMacro1          ' Call your macro
    ActiveWorkbook.Save    ' Save the current workbook, bypassing the prompt
    Application.Quit       ' Quit Excel
End Sub

This will now return the control to your batch file to do other processing.

@ Robert: I have tried to adapt your code with a relative path, and created a batch file to run the VBS.

The VBS starts and closes but doesn't launch the macro... Any idea of where the issue could be?

Option Explicit

On Error Resume Next

ExcelMacroExample

Sub ExcelMacroExample() 

  Dim xlApp 
  Dim xlBook 

  Set xlApp = CreateObject("Excel.Application")
  Set objFSO = CreateObject("Scripting.FileSystemObject")
  strFilePath = objFSO.GetAbsolutePathName(".") 
  Set xlBook = xlApp.Workbooks.Open(strFilePath, "Excels\CLIENTES.xlsb") , 0, True) 
  xlApp.Run "open_form"


  Set xlBook = Nothing 
  Set xlApp = Nothing 

End Sub

I removed the "Application.Quit" because my macro is calling a userform taking care of it.

Cheers

EDIT

I have actually worked it out, just in case someone wants to run a userform "alike" a stand alone application:

Issues I was facing:

1 - I did not want to use the Workbook_Open Event as the excel is locked in read only. 2 - The batch command is limited that the fact that (to my knowledge) it cannot call the macro.

I first wrote a macro to launch my userform while hiding the application:

Sub open_form()
 Application.Visible = False
 frmAddClient.Show vbModeless
End Sub

I then created a vbs to launch this macro (doing it with a relative path has been tricky):

dim fso
dim curDir
dim WinScriptHost
set fso = CreateObject("Scripting.FileSystemObject")
curDir = fso.GetAbsolutePathName(".")
set fso = nothing

Set xlObj = CreateObject("Excel.application")
xlObj.Workbooks.Open curDir & "\Excels\CLIENTES.xlsb"
xlObj.Run "open_form"

And I finally did a batch file to execute the VBS...

@echo off
pushd %~dp0
cscript Add_Client.vbs

Note that I have also included the "Set back to visible" in my Userform_QueryClose:

Private Sub cmdClose_Click()
Unload Me
End Sub

Private Sub UserForm_QueryClose(Cancel As Integer, CloseMode As Integer)
    ThisWorkbook.Close SaveChanges:=True
    Application.Visible = True
    Application.Quit
End Sub

Anyway, thanks for your help, and I hope this will help if someone needs it
