This blog post provides a VBA macro script that will split every slide that has animations into multiple slides, without keeping the original slides in front of the expanded slides (as is the case in this answer).
The problem that remains with this macro and the other macro, is that the content of a text block with multiple animations is always shown as a whole (e.g. if each sentence of the same text block has a separate animation, all sentences will always be shown together).
VBA Code:
Private AnimVisibilityTag As String
Sub ExpandAnimations()
AnimVisibilityTag = "AnimationExpandVisibility"
Dim pres As Presentation
Dim Slidenum As Integer
Set pres = ActivePresentation
Slidenum = 1
Do While Slidenum <= pres.Slides.Count
Dim s As Slide
Dim animationCount As Integer
Set s = pres.Slides.Item(Slidenum)
If s.TimeLine.MainSequence.Count > 0 Then
Set s = pres.Slides.Item(Slidenum)
PrepareSlideForAnimationExpansion s
animationCount = expandAnimationsForSlide(pres, s)
Else
animationCount = 1
End If
Slidenum = Slidenum + animationCount
Loop
End Sub
Private Sub PrepareSlideForAnimationExpansion(s As Slide)
' Set visibility tags on all shapes
For Each oShape In s.Shapes
oShape.Tags.Add AnimVisibilityTag, "true"
