excel – Looping macro to work on all columns individually without writing long list of repeated transitions

I am trying to loop this macro (below) to go through all me data columns but need some help creating a loop or adjusting the current code to work for all columns.

Sub Trial_5()

'
    ActiveCell.Offset(0, -7).Columns("A:A").EntireColumn.Select
    ActiveWorkbook.Worksheets("Sheet6").Sort.SortFields.Clear
    ActiveWorkbook.Worksheets("Sheet6").Sort.SortFields.Add Key:=ActiveCell, _
        SortOn:=xlSortOnValues, Order:=xlDescending,    DataOption:=xlSortNormal
    With ActiveWorkbook.Worksheets("Sheet6").Sort
        .SetRange ActiveCell.Range("A1:A16395")
        .Header = xlGuess
        .MatchCase = False
        .Orientation = xlTopToBottom
        `enter code here`.SortMethod = xlPinYin
       .Apply
    End With
End Sub

do I adjust the .columns or the activecell.offset to total range??

    On Error Resume Next  '<~~ may be necessary if a column breaks the sort 
    With Worksheets("Sheet5")
        For c = .UsedRange.Columns.Count To 1 Step -1
            With .Columns(c)
                .Cells.Sort Key1:=.Columns(1), Order1:=xlDescending, _
                            Orientation:=xlTopToBottom, Header:=xlGuess
            End With
        Next c
    End With
End Sub
