Yes of course.  Start by working out how to upload the file.  Google
rails file upload to get suggestions.

Yes.

Which bit are you stuck on? Uploading a file? Reading each row? or
Checking the certain criteria?

That should be much easier than uploading the file.  I think some
basic Ruby tutorials would be in order (Ruby rather then Ruby on Rails
as this is a Ruby issue not a Rails one).  You cannot develop a Rails
app without a good knowledge of Ruby.
