I'm creating a monster

I am an amateur jQuery user and I'm replicating a spreadsheet from excel into jQuery drop down choices. At this point I've got 3300 lines of code and 214,000 characters. I'm just looking for feedback from others to see is this normal? Most of my code is for placing data into arrays and then I seem to be repeating a lot of commands when I show the data in my drop down list.
