Right-To-Left sheets

Hello,

I would like to write a macro that changes the orientation of the whole sheet (from right-to-left to left-to-right and vice versa).
That is, if the columns are ordered from the left to the right (where the 'A' column is in the top left corner), after the macro
the columns will start from the right (where the 'A' columns' will be in the top right corner).

Thanks a lot
