Wufoo - Paid (unless you have small requirements), but awesome. Non-install, but you create the forms there and then install them in your webpage. You can bulk-export to excel or CSV.

FormTools - Free, open-source, self-hosted. Does all that you need, but isn't as simple to use as Wufoo. However, it is simple to use and I like it a lot.
