Google sprinkled in the ability to edit Microsoft Office files in Drive a while back, but the folks in Mountain View are always looking to help improve that workflow. When a colleague sends a non-Google file as an attachment, you're now able to convert those to Drive-friendly files right inside Gmail. Need to send back the proper .docx? No worries. Installing a Chrome extension enables you to edit the file without making the switch. What's more, over a dozen more Office formats have been added to the productivity feature.
