In your post you didn't mention which excel version you are using..
If it is 2003 use this:-
Tools>>Options>>International>>Right to left>>Uncheck the View Current Sheet
Right to Left
If it is 2007 use this:-
Click the Office Ribbon Button(colorful round circle at the top Left
corner)>Excel Options>Advanced>Customize Quick>Access Toolbar> Choose
commands from>All Commands>and select “Right to Left Document†and click Add
and give OK.
Now in your excel menu window you can able to see a small Icon with a left
indication symbol will be available nearby the Save (Floppy Icon). Just
click it to Make the sheet view to show the columns XFD to A and press once
again that left indication icon to make it from A to XFD.
