How do save as in Numbers and keep original

[alainr]

I am using Numbers 3.6.2 on my mac w/el capitan version 10.11.6.
How do you do a SAVE AS and keep the original spreadsheet?
I made changes to my Spreadsheet #1, hit the option key and then the Save As choice appeared and saved the new Spreadsheet #2.
But then, Spreadsheet #1 had all the changes I made for #2--it didn't remain the way it started.

Is there a way to do a save as and keep the original in its original form?

File --> Duplicate will make a copy of the original file. Any changes you make before you Duplicate are saved to the original, so make the Duplicate BEFORE you make unwanted changes to the original.

That is great if i plan it out beforehand. but sometimes i just start making corrections and realize that i want to keep t he original version and one w/my new changes.

You would have to make a Duplicate, then go back to the original and undo everything.
