My next school project is in microsoft excel. However school are using 2007 and it seems to be rather expencive. Now I could use skydrive/google spreadsheets to do it however it needs to be handed in, in xlsx format. Therefore it would be wise to just get office at home.
Therefore, I'm stuck between microsoft 365 and office home & student 2013. Which is better? Also which of these are compatible with office 2007? I know there's google and I have looked but couldn't really find much.
One last thing have any of you gto any good sites for buying software like this? Cheap-ish :)
