VBA PowerPoint

Excel VBA PowerPoint

Using VBA we can automate the work we do for PowerPoint, but first in order to use VBA code or snippets to work in powerpoint first work through the security options in PowerPoint to enable all macros and then we can use PowerPoint VBA reference for macros in MS PowerPoint.

The beauty of VBA is that we can reference other Microsoft products like “Microsoft Word” and “Microsoft PowerPoint”. We usually create reports in excel and then create PowerPoint presentations. All the excel users usually spend a considerable amount of time to prepare the presentation from excel data and reports. If you are spending a considerable amount of time preparing PowerPoint presentations this tutorial will show you how to create a PowerPoint presentation from excel itself using VBA Coding.

Enable Powerpoint Object Model

Step 1: Open VBA Editor and then, Go to Tools and References.

Step 2: Now you will see all the references to the VBA Project. Scroll down and select “Microsoft PowerPoint 15.0 Object Library”.

Step 3: Click on Ok. Now we can access PowerPoint from excel.

VBA Tutorial to Create PowerPoint Presentation

We can create PPT in two way one by using “Early Binding” and another one is using “Late Binding”. We will show you how to create a PowerPoint presentation by using the “Early Binding” technique.

Usually, from excel we prepare presentations based on charts and interpretation of the charts. So for this purpose, I have created some simple excel charts and interpretation in the same worksheet.

Step 1: Start the subroutine in vba. Now to access PowerPoint we have already enabled the PowerPoint object model in the earlier steps, now to access this we need to declare the variable as PowerPoint.Application.

Code:

Sub PPT_Example()
   
    Dim PPApp As PowerPoint.Application
End Sub

Step 2: To add the presentation to PowerPoint we need to declare a variable as PowerPoint.Presentation.

Code:

 Dim PPPresentation As PowerPoint.Presentation

Step 3: After adding the presentation to the PowerPoint we need to add Slide. To declare the variable as PowerPoint.Slide

Code:

Dim PPSlide As PowerPoint.Slide

Step 4: Once the slide is added to the PowerPoint we need to make use of shapes in the PowerPoint i.e. text boxes. To declare a variable as PowerPoint.Shape

Code:

Dim  PPShape As  PowerPoint.Shape

Step 5: Now to access all the charts in the worksheet we need to declare the variable as Excel.ChartObjects.

Code:

Dim PPCharts As Excel.ChartObject

Ok, to start off the proceedings these variables are enough.

Step 6: Now we need to launch the PowerPoint from excel. Since it is an external object we need to set this as a new powerpoint.

Code:

Set PPApp = New PowerPoint.Application

This will launch the new PowerPoint from excel.

Step 7: Now the variable PPApp is equal to the PowerPoint we have launched. Now make this PowerPoint visible and maximize the window.

 Code:

PPApp.Visible = msoCTrue
PPApp.WindowState = ppWindowMaximized

At this moment just run the code using F5 key or manually, you should see PowerPoint app launched like the below one.

Step 8: Now we need to add a presentation to the PowerPoint app we have launched.

Code:

Set PPPresentation = PPApp.Presentations.Add

Now we should see the PowerPoint presentation like this.

Step 9: After adding the presentation we need to add a slide.

Code:

Set PPSlide = PPPresentation.Slides.Add(1,  ppLayoutTitleOnly)

Now this will add the title slide like the below.

Step 10:  Now we have more than one chart in the worksheet we need to loop through each chart and paste in the presentation. Below is the code to copy and paste the chart as well as interpretation.

Below is the complete code for you.

Sub PPT_Example()

    Dim PPApp As PowerPoint.Application
    Dim PPPresentation As PowerPoint.Presentation
    Dim PPSlide  As PowerPoint.Slide
    Dim PPShape As PowerPoint.Shape
    Dim PPCharts As Excel.ChartObject

    Set PPApp = New PowerPoint.Application

    PPApp.Visible = msoCTrue
    PPApp.WindowState = ppWindowMaximized

    'Add Presentation
     Set PPPresentation = PPApp.Presentations.Add

     'Loop through each chart in the Excel and paste into the PowerPoint
     For Each PPCharts In ActiveSheet.ChartObjects
       PPApp.ActivePresentation.Slides.Add PPApp.ActivePresentation.Slides.Count + 1, ppLayoutText
       PPApp.ActiveWindow.View.GotoSlide PPApp.ActivePresentation.Slides.Count
       Set PPSlide = PPApp.ActivePresentation.Slides(PPApp.ActivePresentation.Slides.Count)

    'Copy the chart and paste in Powerpoint
     PPCharts.Select
     ActiveChart.ChartArea.Copy
     PPSlide.Shapes.PasteSpecial(DataType:=ppPasteMetafilePicture).Select

    'Add heading to the slide
     PPSlide.Shapes(1).TextFrame.TextRange.Text = PPCharts.Chart.ChartTitle.Text

    'Allignment of the chart
     PPApp.ActiveWindow.Selection.ShapeRange.Left = 15
     PPApp.ActiveWindow.Selection.ShapeRange.Top = 125

     PPSlide.Shapes(2).Width = 200
     PPSlide.Shapes(2).Left = 505

     'Add interpretation
        If InStr(PPSlide.Shapes(1).TextFrame.TextRange.Text, "Region") Then
           PPSlide.Shapes(2).TextFrame.TextRange.Text = Range("K2").Value & vbNewLine
           PPSlide.Shapes(2).TextFrame.TextRange.InsertAfter (Range("K3").Value & vbNewLine)
     'Else if the chart is the "Renewable" consumption chart, then enter the appropriate comments
         ElseIf InStr(PPSlide.Shapes(1).TextFrame.TextRange.Text, "Month") Then
           PPSlide.Shapes(2).TextFrame.TextRange.Text = Range("K20").Value & vbNewLine
           PPSlide.Shapes(2).TextFrame.TextRange.InsertAfter (Range("K21").Value & vbNewLine)
           PPSlide.Shapes(2).TextFrame.TextRange.InsertAfter (Range("K22").Value & vbNewLine)
      End If

   'Now let's change the font size of the callouts box
      PPSlide.Shapes(2).TextFrame.TextRange.Font.Size = 16

Next PPCharts

End Sub
