      Hello, Cenk,
      The macro name is the macro code you have inserted into the Excel file, and you just need to change the Macro1 in the above code to your own.
      For example, i insert a code here, and the macro name is: ColorCompanyDuplicates

      Sub ColorCompanyDuplicates()
      'Updateby Extendoffice 20160704
      Dim xRg As Range
      Dim xTxt As String
      Dim xCell As Range
      Dim xChar As String
      Dim xCellPre As Range
      Dim xCIndex As Long
      Dim xCol As Collection
      Dim I As Long
      On Error Resume Next
      If ActiveWindow.RangeSelection.Count > 1 Then
      xTxt = ActiveWindow.RangeSelection.AddressLocal
      Else
      xTxt = ActiveSheet.UsedRange.AddressLocal
      End If
      Set xRg = Application.InputBox("please select the data range:", "Kutools for Excel", xTxt, , , , , 8)
      If xRg Is Nothing Then Exit Sub
      xCIndex = 2
      Set xCol = New Collection
      For Each xCell In xRg
      On Error Resume Next
      xCol.Add xCell, xCell.Text
      If Err.Number = 457 Then
      xCIndex = xCIndex + 1
      Set xCellPre = xCol(xCell.Text)
      If xCellPre.Interior.ColorIndex = xlNone Then xCellPre.Interior.ColorIndex = xCIndex
      xCell.Interior.ColorIndex = xCellPre.Interior.ColorIndex
      ElseIf Err.Number = 9 Then
      MsgBox "Too many duplicate companies!", vbCritical, "Kutools for Excel"
      Exit Sub
      End If
      On Error GoTo 0
      Next
      End Sub

    What's the point of the condition? It'll always return true...in other words: it'll run without it. This also runs whenever any cells on the sheet change value.

    Thanks a lot! This really helped me out.
    Is there any method to retrieve the address of the changed cell (with formula i.e Column C in this example).
    Thanks.
