SUMMARY
This article provides a sample Microsoft Visual Basic for Applications macro (Sub procedure) that searches a presentation for linked Excel OLE objects and changes the linked source of these objects to a single source workbook that you specify. This macro retains links to specific spreadsheet ranges and objects, and allows you to change the source workbook.

This macro assumes that the linked objects are all Excel Spreadsheet objects and that the links are to sections of spreadsheets, and not to entire workbooks.

Sample Visual Basic Procedure
Sub ChangeExcelSource

Dim i As Integer Dim k As Integer

' Create a variable to store the worksheet reference string. Dim linkname As String

' Create a variable to store the position of the worksheet ' reference in the .SourceFullName property of the OLEFormat ' object. Dim linkpos As Integer

' Set a For loop to go from slide 1 to the last slide in the ' presentation. For i = 1 To ActivePresentation.Slides.Count

' Select the slide based on the index value. With ActivePresentation.Slides(i)

' Loop through all the objects on slide. For k = 1 To .Shapes.Count

' Use only shapes on the slide. With .Shapes(k)

' If the shape's type is an OLE object then... If .Type = msoLinkedOLEObject Then

' Change the path to new source and set the update ' type to Automatic. First find where the worksheet ' reference is, and then store it in linkname. Next ' assign the new path and concatenate the chart name ' to the end of the path. With .LinkFormat

' Find where in the source path string the ' character "!" occurs, and assign the position ' to the variable linkpos. linkpos = InStr(1, .SourceFullName, "!", _                   vbTextCompare)

' Assign linkname to worksheet reference at the ' end of the source file path. linkname = Right(.SourceFullName, _                   Len(.SourceFullName) - linkpos) .SourceFullName = "c:\document\fileb.xls!" & linkname .AutoUpdate = ppUpdateOptionAutomatic End With

End If

End With

Next k

End With

Next i

' Update all links in the presentation, so that the changes are ' visible and the source file locations are correct on the screen. ActivePresentation.UpdateLinks End Sub
