Function ConvertToLetter(iCol As Integer) As String    ' Dim iAlpha As Integer    ' Dim iRemainder As Integer    ' iAlpha = Int(iCol / 27)    ' iRemainder = iCol - (iAlpha * 26)    ' If iAlpha > 0 Then    ' ConvertToLetter = Chr(iAlpha + 64)    ' End If    ' If iRemainder > 0 Then    ' ConvertToLetter = ConvertToLetter & Chr(iRemainder + 64)    ' End If    Dim columnName As String    Dim modulo As Integer    While iCol > 0    modulo = (iCol - 1) Mod 26    columnName = Chr(65 + modulo) + columnName    iCol = Int((iCol - modulo) / 26)    Wend    ConvertToLetter = columnName    End Function
