Alright, this was pretty fun... try this.

Go to

Tools-- Macro --- Visual Basic Editor

The in the Visual Basic Editor go to

Insert --- Module

Then Copy and paste this exactly as is, in to the module

Sub cols()
For x = 1 To 26

ActiveCell.Formula = "=LEFT(ADDRESS(1," & x & ",2),1)"
ActiveCell.Offset(1, 0).Activate

Next x

For x = 27 To Columns.Count
ActiveCell.Formula = "=LEFT(ADDRESS(1," & x & ",2),2)"
ActiveCell.Offset(1, 0).Activate
Next x

End Sub

Then select the cell where you want the columns letters to start. So the
cell where you want A. Then go to

Tools--- Macro--- Macros

And then click on the macro colled "cols" and then press play and watch the
magic!
