CollateBox is a free online (beta) service, by invite (request one on their site) that allows you to organize and collaborate on spreadsheet data. Copy and paste existing data from a spreadsheet into Collatebox, set filters, hide columns, set up views for different people and then update it. One of the big features that set it apart is that you can limit what data each person sees and customize their views, all while keeping the master data updated.
This could be useful for school data teams, administrators, and students working on projects.
