Do you still believe Google can't do everything Word can do? Google Sheets now allows you to rotate the text! (Format > Text Rotation) This is very useful when you need to fit a long header name into thin columns, or when you want to fit more text on one screen.
Simply select the desired cell/s, select Format, and text rotation. You can then choose from a variety of styles including stacking vertically or angled to any of the above angles.
