If you mean you want to*globally* convert all text in a sheet to Upper Case,
I don't know of a way to do so in Mac XL.
The UPPER function is more for displaying the content of referenced cells in
upper case regardless of how it was typed into the cells where it is
actually stored.
If the latter is what you are trying to do, see Excel Help on the UPPER
function, but it's rather straightforward...
If cell A1 contains the word [help] or [Help] (or any variation on case for
that matter) and in cell B1 you put:
=UPPER(A1)
Cell B1 will display [HELP]
