Google Sheets App Script Fix

I have a Google Sheets workbook with a mostly complete script, but I have hit a wall; each fix causes another issue or reverts to the original one. Is it possible to make a copy of the workbook so I can see what I am working with? ALL data in this document is fake and made up...
