Create new PowerPoint presentation from PowerPoint template using VBA in Excel

Question

I have an Excel macro that opens a PowerPoint file from a specified location. The PowerPoint file is a template.

I need to create a new presentation based on the template design.

My code will open the template rather than a new presentation based on that template:

Sub Open_PowerPoint_Presentation()
    'Opens a PowerPoint Document from Excel
    
    Dim objPPT As Object
    
    Set objPPT = CreateObject("PowerPoint.Application")
    objPPT.Visible = True
    
    'Change the directory path and file name to the location
    'of your document
    
    objPPT.Presentations.Open "C:\Users\Colin\Documents\Custom Office Templates\PowerPoint Templates\Edge45 Monthly Report Template Macro.potm"
    
End Sub

Answer 1

In my opinion, you should open your template file with the Untitled parameter ( Open method) set to true.

objPPT.Presentations.Open FileName:="MyTemplate Macro.potm", Untitled:=msoTrue

According to Presentations.Open Method (PowerPoint) ,

Opens the file without a title. This is equivalent to creating a copy of the file.
