Chrome Unboxed: Google Docs, Sheets, and Slides will now warn you of Office file compatibility issues
Chrome Unboxed: Google Docs, Sheets, and Slides will now warn you of Office file compatibility issues. “First and foremost, a new warning indicator will appear if your file has compatibility issues in Drive. It will appear and stay for the entirety of your editing session or so long as there are problems to be certain you address them before shipping the document off to its recipient.”
