Convert embed charts in PPT to enhanced metafiles

[wolis]

Hi, I have a 70+ slide PPT presentation with embed charts from Excel that all need to be converted to pictures (so that data wouldn`t be accessible).

I have tried to compile a script that would loop through all slides, find all shapes, copy, delete and then paste them back. After that I`ll try to find a way for it to check if shapes are actually charts.

This is my first time trying to create a macro (I have no experience with VBA) so I guess there might be some silly mistakes.

So far I have got this:


Sub ConvertCharts()
Dim SlideToCheck As Slide
Dim ShapeIndex As Integer
' Visit each slide
For Each SlideToCheck In ActivePresentation.Slides
' On each slide, count down through the shapes
For ShapeIndex = SlideToCheck.Shapes.Count To 1 Step -1
' Copy, delete, Paste
SlideToCheck.Shapes(ShapeIndex).Copy
SlideToCheck.Shapes(ShapeIndex).Delete
Application.ActiveWindow.View.PasteSpecial DataType:=ppPasteEnhancedMetafile
Next
Next
End Sub

With this it shows an error at line "SlideToCheck.Shapes(ShapeIndex).Copy" , Shapes (unknown member) : Integer out of range. 0 is not the valid range of 1 to 0.

I`d be glad if someone could at least point me in the right direction.:help

I have now come up with this:

Sub ConvertCharts()
Dim oShape As Shape
Dim oPresentation As Presentation
Dim oSlide As Slide
Dim oSelection As Selection
Dim l As Double
Dim t As Double
Set oPresentation = ActivePresentation
Set oSelection = Application.ActiveWindow.Selection
For Each oSlide In oPresentation.Slides
For Each oShape In oSlide.Shapes
oSlide.Select
oShape.Select
l = oShape.Left
t = oShape.Top
oShape.Copy
oShape.Delete
Application.ActiveWindow.View.PasteSpecial DataType:=ppPasteEnhancedMetafile
' Get the index of last insertion'
i = ActivePresentation.Slides(ActiveWindow.Selection.SlideRange.SlideNumber).Sh apes.Count
' Select the last inserted object'
ActiveWindow.Selection.SlideRange.Shapes(i).Select
With ActiveWindow.Selection.ShapeRange
.Left = l
.Top = t
End With
Next oShape
Next oSlide
' If Not oSelection Is Nothing Then
' oSelection.Select
' End If
End Sub

It seems to work, but it skips some of the charts ( For example 3 charts in a slide 2 are converted, 1 is not. In another almost identical slide 1 is converted 2 are not). Anyone know why?

I don't see how you would get that error but you would have to account for placeholders with charts which act in a special way (they create a blank copy when you delete them) as well as just charts.

See if this gets you going


Sub ConvertCharts()
Dim SlideToCheck As Slide
Dim ShapeIndex As Long
Dim ThisShape As Shape
Dim myLeft As Single
Dim myTop As Single
' Visit each slide
For Each SlideToCheck In ActivePresentation.Slides
' On each slide, count down through the shapes
For ShapeIndex = SlideToCheck.Shapes.Count To 1 Step -1
Set ThisShape = SlideToCheck.Shapes(ShapeIndex)
' Is shape a placeholder
If ThisShape.Type = msoPlaceholder Then
If ThisShape.HasChart Then
ThisShape.Cut
SlideToCheck.Shapes(SlideToCheck.Shapes.Count).Select
ActiveWindow.View.PasteSpecial (ppPasteEnhancedMetafile)
End If
Else
If ThisShape.HasChart Then
myLeft = ThisShape.Left
myTop = ThisShape.Top
ThisShape.Cut
With SlideToCheck.Shapes.PasteSpecial(ppPasteEnhancedMetafile)
.Left = myLeft
.Top = myTop
End With
End If
End If
Next
Next
End Sub

Yes, this did the trick! Thanks :)

This is the code I am using, if it is any help to you or if there's anything here that you might want to incorporate into your methods. I have stripped it down from a larger function to (hopefully) include only the code necessary to convert the charts. It should do what you want.
