I too have the same issue - I have Office but cannot assume all the 'users' do, so I am struggling with Open/Libre Office. I would suggest that is the best way to go for you although getting to grips with it is very hard work. The documentation (for beginners) is poor and fragmented and the so-called 'Help' forums seem to have more that their fair share of those who just cannot bring themselves to help we lesser mortals pick up the threads. It is a shame, as the concept of an O Source alternative to the MS giant is good and deserves better support. I actually had to ask for one mod to be 'de-modded' for appalling behaviour (shades of PPrune..................) - I think he/she actually had a mental problem.
If it is any consolation I am getting through the conversion of a large VBA project into OO, slowly and painfully, and so far so good...................
