Hello! New to all this. Hope this question is not inappropriate. New PC and just added 365. I've used MS for a long time. However, I'm in EXCEL this morning and can't find something as simple as splitting a cell. MS has somewhat complicated adding a command to my main ribbon so I can't move the command that I have found "split the cell." When I click to move it to a list, it now tells me I have to select or initiate a new "group." Any help will be most appreciated.
