Free Google Add-Ons for Google Docs and Google Sheets

These Google Drive add-ons are a must-have for efficiency and ease of use

Screenshot of some of the available Google Docs Add-ons.

Writers and communicators exert a lot of effort to convey a story or message. If you use the free, online Google Docs program or the business Google G Suite, add-ons can make the process much simpler.

Add-ons are tools you can add to a Google app's program's toolbar, as opposed to a template, which is a pre-made document. You may have heard these called add-ins, third-party apps, or extensions. Each office software suite has its own terminology.

Most users are able to log in to Google Docs through their Google Drive or Gmail sign-in.

In Google Drive, you can add apps to Google Docs, Google Sheets, or other Google apps simply. Just select Settings > Manage Apps > Connect more apps. To add apps from within Docs, Sheets, or other apps, click the Add-ons tab in the top toolbar and then select Get add-ons.

A lot of free add-ons are available, but communication professionals are busy, and there are tons of apps to cull through. We've highlighted those we considered most useful in an effort to save you some time.
