DOCX files, directly in Google's browser. Word Online is a Chrome app that lets you view, edit and create.

In case Word is the only Office tool that you actually use, there's no need for you to install the entire Office add-on. The only disadvantage is that the output files can only be saved on an OneDrive or OneDrive Business accounts, so you will need to have one of those in order to use the extension. Office Online is an add-on that allows you to create Word, Excel, PowerPoint, OneNote and Sway files or edit any of the previously mentioned formats, directly in your web browser. This extension comes from Microsoft itself, as the company has finally decided to admit Chrome's supremacy over Edge or Internet Explorer. As far as I'm concerned, Office Online is the best Chrome tool to help you deal with Office files.
