Changing the width of an Excel column to accommodate all text in a single line is something I do frequently while working with MS Excel worksheets.

After a while it gets tiresome to select Format > AutoFit Column Width from the ribbon all the time.
So here is a wonderful Windows short cut that will fit your text automatically to a column by expanding the column width:

Alt + O, C, A

(1) First, select the column the width of which you’re trying to change.
(2) Press the Alt key, then O, C, and A keys in succession.
It works every time like a charm.
