Question

Is there any way to run an Excel Macro in CSV file format?

I am exporting a file to CSV using a csv template, Is it possible to write macros on the template which is in CSV format. I cant have it in XLS format. Can anyone help me on this?

Answer 1

While you can’t save a macro inside a CSV file you can either

1. Run the macro on the CSV using a controller workbook, or an addin
2. Go a step further and programmatically add code to the CSV file (for example to add an Event handler)

If you provide more information as to what you need to do then we can help with the paths above.

(Edit: it still isn’t clear how the CSV file is generated – is this done via Excel or by another app?]

Using Pearson’s Application Events example you could use the code at bottom (from an open Excel controller workbook) to capture the addition of a new CSV file and then format it.

If you need to catch the creation of the CSV file on the fly then a more complex approach such as using VBscript with WMI is necessary.

Controller Workbook Approach

ThisWorkbook Module

Private XLApp As CExcelEvents

Private Sub Workbook_Open()
    Set XLApp = New CExcelEvents
End Sub

class module called CExcelEvents

Private WithEvents App As Application

Private Sub App_NewWorkbook(ByVal Wb As Workbook)
If Wb.FileFormat = xlCSV Then
MsgBox Wb & " is a Csvfile"
'your code
End If
End Sub

Private Sub Class_Initialize()
    Set App = Application
End Sub
