can an expert provide the answer to this in the form of VBA code?

I need to remove all duplicates from all rows

so I could have 10, 20 30 rows of

AIOF,AIOF,AIOF,AIOF,AIOFPLC,AIOFPLC,AMHH,AMHH,APFT,APFT,BUNP,BUNP,BUNP,BUNP,EGTO,EGTO,EGTO,EGTO
AIOF,AIOF,AIOF,AIOF,AIOFPLC,AIOFPLC,AMHH,AMHH,APFT,APFT,BUNP,BUNP,BUNP,BUNP,EGTO,EGTO,EGTO,EGTO
AIOF,AIOF,AIOF,AIOF,AIOFPLC,AIOFPLC,AMHH,AMHH,APFT,APFT,BUNP,BUNP,BUNP,BUNP,EGTO,EGTO,EGTO,EGTO

and I only want one occurance of each , so if I have 3 rows like the above I want to end up with in row like the below. [this can be put on a new worksheet]

AIOF,,AIOFPLC,AMHH,APFT,APFT,BUNP,EGTO,


thanks

And what should happen with

AIOF,AIOF,AIOF,AIOF,AIOFPLC,AIOFPLC,AMHH,AMHH,APFT,APFT,BUNP,BUNP,BUNP,BUNP,EGTO,EGTO,EGTO,EGTO
AIOF,AIOF,AIOFPLC,AMHH,AMHH,APFT,APFT,BUNP,BUNP,EGTO,EGTO

are those also duplicates?
And can the original worksheet be modified (i.e. duplicates removed here)?

Hey Jagwrman,

run this code on the selection    make sure you run the macro called remDupstringsComma

Sub remDupstringsComma()
   ' Comma Separator
Dim dic As Object, cell As Range, temp As Variant
Dim i As Long
Set dic = CreateObject("scripting.dictionary")
With dic
    For Each cell In Selection
        .RemoveAll
        If Len(cell.Value) > 0 Then
            temp = Split(" " & cell.Value, ",")
            For i = 0 To UBound(temp)
                If Not .Exists(temp(i)) Then .Add temp(i), temp(i)
            Next i
            cell.Value = Mid(Join(.Keys, ","), 2)
        End If
    Next cell
End With
        Call RemoveDuplicateRows
End Sub

Sub RemoveDuplicateRows()
    Application.ScreenUpdating = False
    Dim ColN As Long
    Dim MyS As Worksheet: Set MyS = ActiveSheet
    Dim MyR As Range: Set MyR = MyS.Cells(1, 1).CurrentRegion
    Dim NumCol As Long: NumCol = MyR.Columns.Count
    Dim MyArray As Variant: ReDim MyArray(0 To NumCol - 1)
    For ColN = 1 To NumCol
        MyArray(ColN - 1) = ColN
    Next
    MyR.RemoveDuplicates Columns:=(MyArray), Header:=xlYes
    Dim rowcount As Long, i As Long, j As Long, k As Boolean
    rowcount = MyR.Rows.Count
    For i = rowcount To 1 Step -1
        k = 0
        For j = 1 To NumCol
            If MyR.Value2(i, j) <> "" Then
                k = 1
                Exit For
            End If
        Next j
        If k = 0 Then
            MyR.Rows(i).Delete Shift:=xlUp
        End If
    Next i
    Application.ScreenUpdating = True
End Sub
