If you are using the "Online" Browser-based software...NO.....not if you are using the same Online account. You would have to create an entirely new account (with new UserID and Pwd ), and that new account would require you to start from scratch.
_______________
If you are using the Desktop software...YES.
First Save your real file, then do a Save-As, but make sure you change the filename when saving to something simple like "Test_File". Then you can work with that test file as much as you want.
Note that in the Desktop software there is also a What-IF worksheet you can open if Forms Mode, that you can mess with, and it does not affect the main form...just that worksheet....but there is no Q&A to lead you thru it, you just copy columns & change numbers.
