Open Power Point and Refresh Excel Charts

[Richynero]

Hi there,

I have a challenge where I have to loop through all PowerPoint files in a folder/subfolders and refresh the charts within them. These charts are shared on MS Teams and SharePoint and are not updating when the Excel files are amended. I have built the code to loop through the directory and open them but I am now struggling to get them to refresh. Apparently this code should work but this code will need to sit in every power point file (Update PowerPoint chart using VBA). Any ideas?

Here is the code that runs within PowerPoint to refreh the charts. Thing is I dont want this sitting in each PowerPoint.

Sub UpdateLinks()

    'Declare PowerPoint Variables
    Dim PPTSlide As Slide
    Dim PPTShape As Shape
    Dim SourceFile, FileName As String
    Dim Position As Integer

    'Declare Excel Variables
    Dim xlApp As Excel.Application
    Dim xlWorkBook As Excel.Workbook

   
    'Loop through each slide in the Presentation.
    For Each PPTSlide In ActivePresentation.Slides

        'Loop through Each Shape in the slide
        For Each PPTShape In PPTSlide.Shapes

            'If the Shape is a linked OLEObject.
            If PPTShape.Type = msoLinkedOLEObject Then

                    'Update the link
                    PPTShape.LinkFormat.Update

            End If

        Next PPTShape
    Next PPTSlide


End Sub
