VBA PowerPoint

Using VBA, we can automate the work we do for PowerPoint. But first, to use VBA code or snippets to work in PowerPoint, first work through the security options in PowerPoint to enable all Macros. 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 Excel users usually spend a considerable amount of time preparing the presentation from Excel data and reports. If you spend considerable time preparing PowerPoint presentations, this tutorial will show you how to create a PowerPoint presentation from Excel using VBA Coding.

We can create PPT in "Early Binding" and "Late Binding." Finally, we will show you how to create a PowerPoint presentation using the “Early Binding” technique.

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

Step 1: Start the subroutine in VBA. We have already enabled the PowerPoint object model in the earlier steps to access PowerPoint. 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 a Slide to declare the variable as PowerPoint.Slide.

Code:

Dim PPSlide As PowerPoint.Slide

Step 4: Once we add the slide to the PowerPoint, we need to use shapes in the PowerPoint, i.e., text boxes, to declare a variable as PowerPoint.Shape.

Code:

Dim  PPShape As  PowerPoint.Shape

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

Code:

Dim PPCharts As Excel.ChartObject

These variables are enough to start the proceedings.

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

It will launch the new PowerPoint from Excel.

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

 Code:

PPApp.Visible = msoCTrue
PPApp.WindowState = ppWindowMaximized

Now, just run the code using the F5 key or manually. You should see the PowerPoint app launched like the one below.

Step 8: 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: We need to add a slide after adding the presentation

Code:

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

Now, this will add the title slide like the below.

Step 10:  Now that we have more than one chart in the worksheet, we need to loop through each chart and paste it into the presentation. Below is the code to copy and paste the chart and 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
