Changing the output of a javascript form, from a server to excel file.

[iMAN2]

Basically i have this html file with a quiz on it which submits the results to a server (using javascript) and then returns the mark.

I want to use this html file for offline veiwing, so i've saved the complete webpage. Now i can still select the radio buttons for options a,b,c,d, but if i click the submit button, it will try and send the form results to the server, but i want to use this for offline veiwing. So i want to change the submit button so it saves the form results in an excel file, which i can then manually check.
