Torah613Torah: I use LibreOffice Calc as my primary spreadsheet at home. There are tons of tutorials online. Once you get the hang of it, it’s fairly simple to learn. Google Docs is another great option as it saves all your data online so you always have it backed up and can access it wherever you have internets.
crazybrit: The reason I reccomend OpenOffice and LibreOffice over Excel is that they are free while Excel costs a lot of money. For these purposes, they do everything you need and more.
