Web Export files are minified.

I have tried to export the course for web, It does let me download a zip file of the course. However, the source code is minified. And I am not able to edit the source code to add some custom logic. Say I want to add course completion tracking by modifying that button click event. My question is, is there any way to download the course unminified? And no, I do not want the LMS export.
