Add-ons in Google Docs can be used to improve the functionality and efficiency during your experience with Google Docs.
When you’re in Google Docs, click on the “Add-ons” tab on the top left corner of your screen. Then, click on “Get add-ons…” to bring you to the Add-on catalog.
On the Add-on catalog, most of the Add-ons are free. You can search for them or window-shop for them.
Once you’ve added you Add-on, opening it is very simple. Just click on the “Add-on” tab and click on one of the add-ons that you’ve just added.
Finally, just wait until the add-on starts and you can use it right away.
