What version of excel are you using? In 2002 I can type H2O into a cell
then highlight just the 2, right click, format, subscript.

I would like to make some custom formats with text that has superscript
such
as the 3 in m3/d or subscript as the 2 H20. There doesn't seem to be any
formating available in the formating system.
