Tente algo assim. Eu fiz alguns mods para que substitua qualquer instância do texto @ COL1 @ no slide com valores da planilha. Aircode não testado, lembre-se.
Sub CreateSlides()
'Open the Excel workbook. Change the filename here.
Dim OWB As New Excel.Workbook
Set OWB = Excel.Application.Workbooks.Open("C:\list.xlsx")
'Grab the first Worksheet in the Workbook
Dim WS As Excel.Worksheet
Dim sCurrentText As String
Dim oSl As Slide
Dim oSh As Shape
Set WS = OWB.Worksheets(1)
Dim i As Long
'Loop through each used row in Column A
For i = 1 To WS.Range("A65536").End(xlUp).Row
'Copy the first slide and paste at the end of the presentation
ActivePresentation.Slides(1).Copy
Set oSl = ActivePresentation.Slides.Paste(ActivePresentation.Slides.Count + 1)
sCurrentText = WS.Cells(i, 1).Value
' find each shape with "@COL1@" in text, replace it with value from worksheet
For Each oSh In oSl.Shapes
' Make sure the shape can hold text and if is, that it IS holding text
If oSh.HasTextFrame Then
If oSh.TextFrame.HasText Then
' it's got text, do the replace
With oSh.TextFrame.TextRange
.Replace "@COL1@", sCurrentText
End With
End If
End If
Next
Next
