Google has announced new add-ons for Google Docs and Sheets—tools to help you do more in your documents and spreadsheets. For example, you can now print address labels with the Avery Label Merge add-on or create customized mailing list emails with Merge by Mailchimp.
The add-ons are available in the new Add-ons menu. There are more than a handful already available for creating mind maps, sending faxes, document signing, and more. With more likely on the way, Google's web-based office apps might be able to do just about anything you need.
