Gmail web users now have a new and nifty feature to access if they get a lot of Microsoft Office files as email attachments. Google has now set up a way for those files to be converted and edited directly from Gmail via Google Drive.
Google stated that this update will offer Gmail users "the additional benefits of a single document to keep track of, access from anywhere (even offline!), and revision history" with Google Docs, Sheets, or Slides. It also announced that it has added import support for 15 new Office formats into Google Drive. People who want to edit their Office files without converting them to Google's format can do so by installing a Chrome extension. Google stated:
"Once it's in place, you'll have the option to convert the file by clicking on the pencil icon, or edit the file as is by clicking on the attachment card and selecting open from the top of the file preview."
