If you want to change the share link to a forced copy on a Google Doc or Sheet so that it automatically makes a copy instead of allowing direct access to your doc or sheet:
1. Go to the share button for the document or sheet at the top right of your screen and click it.
2.Change the 'restricted access' at the bottom left to 'anyone with a link'
3. Then click on 'Copy link'
4. The end will look something like this: 26E/edit?usp=sharing.
5. Remove all the text AFTER the / and replace it with 'copy' so that it now looks like this: 26E/copy
Now anyone clicks on that link they will be forced to make a copy instead of being able to see your original version.
