I would actually be wary of all online spreadsheets. You are letting very valuable data reside primarily on someone else’s computers. It is harder to backup, migrate, etc. Why not use open office and some type of cloud sync? You are in control of the data. With open formats you can even switch software as you want while keeping your data unaffected.
