A macro might be the simplest way.
If you want to try:
Option Explicit
Sub testme03()
Dim FromRng As Range
Dim DestCell As Range
Dim iRow As Long
Dim TotalCells As Long
Set FromRng = Nothing
On Error Resume Next
Set FromRng = Application.InputBox _
(Prompt:="Select a single column range", Type:=8) _
.Areas(1).Columns(1)
On Error GoTo 0
If FromRng Is Nothing Then
Exit Sub
End If
Set DestCell = Nothing
On Error Resume Next
Set DestCell = Application.InputBox _
(Prompt:="Select a single cell", Type:=8).Cells(1)
On Error GoTo 0
TotalCells = FromRng.Cells.Count
For iRow = 1 To TotalCells
DestCell.Offset(iRow - 1, 0).Value _
= FromRng.Cells(TotalCells + 1 - iRow).Value
Next iRow
End Sub
