csv files can be opened in any text editor including word, notepad, etc.
CSV is a file format that's good for using programming to break the data apart and import/export between different programs that display data in a table/spreadsheet sort of way (excel for example)
if you want a free office-like suite just use open office (google it). their spreadsheet program works enough like excel for you to get buy without buying the actual program. it's what I use on my computers when I don't have access to a free version of MS Office.
edit: serv - we should do something with this

if you can come up with interesting things to analyze statistically I can break it apart really really easily using R
