I have been struggling to come up with a program capable of extracting the 10 most frequent names appearing in a column and storing them into an array for further use.

  • Gather the column's values into an array to speed processing. Transfer to a dictionary's keys with the frequency as each key's item. The worksheet's Large can easily find the 10th largest frequency. Remove anything that has a lower frequency.

    Option Explicit
    
    Sub gfdrew()
        Dim i As Long, j As Long, arr As Variant, k As Variant, dict As Object
    
        Set dict = CreateObject("scripting.dictionary")
    
        With Worksheets("sheet6")
            arr = .Range(.Cells(2, "A"), .Cells(.Rows.Count, "A").End(xlUp)).Value2
        End With
    
        For i = LBound(arr, 1) To UBound(arr, 1)
            dict.Item(arr(i, 1)) = dict.Item(arr(i, 1)) + 1
        Next i
    
        j = Application.Large(dict.items, Application.Min(10, dict.Count))
    
        For Each k In dict.keys
            If dict.Item(k) < j Then dict.Remove (k)
        Next k
    
        arr = dict.keys
    
        For i = LBound(arr) To UBound(arr)
            Debug.Print arr(i)
        Next i
    End Sub
