Newbie-RoR with mysql-excel evolution to web 2.0

Hi folks

Was wondering- would RoR be good to serve up mysql or equal?

Trying to convert an excel file that is used for a proposal tool and
in it, is vlookup, data validation, cocatenate and some financial
calcs etc.

It also creates a proposal as well.

Thinking mysql is the best for the database part, but can RoR with
ajax, jquery etc, serve the other purposes?

Have a video here of what I'm trying to achieve.
