It's easy to open Microsoft Office files directly on your Mac as if they were stored locally on your Mac's hard drive. We'll show you how.
First, you'll need to download the Google Drive desktop application, you can get that here: https://www.google.com/drive/download/
Once you've installed the Google Drive app, close out any Chrome browser windows you have open and then re-open Chrome. Next, open your Mac's Finder window and you'll see you now can browse Google Drive directly from your Mac:
Now just browse to the folder where your file is stored and you can open it just like any file stored on your Mac.
