What you can do is write three loops so

[A..Z].each do |letter|
       [1...num].each do |number|
              #Process the website in here
               process_website letter number
       end
end

As for OOP you could have a Parse class and in and a AppRunner class (which
holds all the websites). the process_website would be in the AppRunner class
and would create a new parser for each website, parse the website and then
either if the websites are indepent (have the parse take care of the writing
to csv), or if dependent in some manner (have the AppRunner write to cvs)
