How to copy Excel charts to PowerPoint automatically using VBA.
Watch the video below:
When creating PowerPoint presentations and making them more useful, we may need many charts from Excel. We can bring these charts from our Excel workbooks to PowerPoint presentation quickly and easily using Visual Basic for Applications (VBA).
Below is the complete VBA code to automate the process of getting charts from Excel into our PowerPoint slides:
Option Explicit
Sub copyexcelchartstopowerpoint()
‘we first set reference to the MS PowerPoint Object Library
Dim PP As PowerPoint.Application
Dim PPPresentation As PowerPoint.Presentation
Dim PPSlide As PowerPoint.Slide
Dim ppSlideCount As Long, SlideCount As Long
Dim i As Long
Sheets(“SalesOrders”).Select
If ActiveSheet.ChartObjects.Count < 1 Then
MsgBox “No charts found!”
Exit Sub
End If
Set PP = New PowerPoint.Application
Set PPPresentation = PP.Presentations.Add
PP.Visible = msoTrue
For i = 1 To ActiveSheet.ChartObjects.Count
ActiveSheet.ChartObjects(i).Chart.CopyPicture Size:=xlScreen, Format:=xlPicture
Application.Wait (Now + TimeValue(“00:00:01”))
ppSlideCount = PPPresentation.Slides.Count
Set PPSlide = PPPresentation.Slides.Add(SlideCount + 1, ppLayoutBlank)
PPSlide.Select
PPSlide.Shapes.Paste.Select
PP.ActiveWindow.Selection.ShapeRange.Align msoAlignCenters, msoCTrue
Next i
‘cleanup memory
Set PPSlide = Nothing
Set PPPresentation = Nothing
Set PP = Nothing
End Sub
