The Best Google Add-ons for Docs, Sheets, Slides and Google Forms

The availability of third-party add-ons for Google Docs, Sheets and Google Slides have certainly made the Google Office productivity suite more capable and useful. If you haven’t tried them yet, open any Google document or spreadsheet in your Google Drive and look for the new add-ons menu near Help. G Suite users may have to ask their admin to enable support for add-ons for the organization.

For starters, Google add-ons are like extensions for Chrome. Extensions add new features to the Chrome browser and add-ons extend the functionality of Google Office applications. To give you an example, here’s the screenshot of a Twitter add-on I wrote for Google Docs and Google Sheets that you can use to find and curate tweets right inside your documents.

Anyone can write an add-on for Google Docs. All you need are some basic programming skills for writing HTML, CSS for styling the add-on while the server side code is written in Google Apps Script which is similar to JavaScript but runs on the Google Cloud.

Google Apps Script vs Google Add-ons

Google Add-ons are written in the Google Apps Script language but while regular Google Scripts can work on any document in your Google Drive, add-ons only work against the document or sheet that’s currently open in your browser.

Also, while Google Scripts support triggers and can run in the background (like this Website Monitor), add-ons can only run while a document or sheet is open and active. (Update: Google now allows you to create time-based triggers for add-ons)

The other big difference is that you can view the source code of regular Google Scripts while in the case of add-ons, the code is hidden from the end user. This helps developers protect their code but a downside is that the user has no clue about what’s happening behind the scenes.

We have seen issues with Chrome extensions and add-ons for Google Docs can be a target as well. For instance, an add-on can possibly email a copy of the current document or sheet to another email address? Or maybe it can share a folder in Google Drive with someone else. All add-ons currently listed in the Chrome store have been tested and reviewed by Google but if they open the gates for all, I would be a little hesitant to install add-ons created by unknown developers.
