Using VBA to Find External Links

If you want to automate the process of finding external links, you can use VBA (Visual Basic for Applications). Here's an example code snippet that finds external links in a workbook:

Sub FindExternalLinks()
    Dim wb As Workbook
    Dim ws As Worksheet
    Dim link As Variant
    
    Set wb = ThisWorkbook
    
    For Each ws In wb.Worksheets
        For Each link In ws.LinkSources
            If link.Type = xlLinkTypeExcelLinks Then
                Debug.Print link.Name
            End If
        Next link
    Next ws
End Sub

This code snippet loops through all worksheets in the active workbook and checks for external links. If an external link is found, it prints the name of the link to the Immediate window.
