How to Add Comments to Microsoft Office Files in Google Drive – No Conversions Required

Imagine saving hours by directly commenting on Microsoft Office documents stored in Google Drive, without any file conversions. Cloud services like Google Drive, OneDrive, and Dropbox make your Word, Excel, and PowerPoint files accessible anywhere. With Google Workspace's interoperability features, you can annotate Office files, PDFs, and images seamlessly—no need for Microsoft Office installations or format switches.

How to Comment on Microsoft Office Files in Google Drive

As a productivity expert with years of experience optimizing workflows for teams, I've relied on this feature countless times. You can open shared Microsoft files in Google Drive, add comments, and they'll appear when viewed in Microsoft Office. It works in preview mode. Follow these simple steps:

  1. Sign in to Google Drive.
  2. Double-click the shared Word, Excel, or PowerPoint file. It opens in preview mode.
  3. In the top right, click Add comment (speech bubble icon). Then select the text, cell, or section to comment on.

  4. Enter your comment and click Comment.
  5. Your team will see the updated file and comments upon opening it.

This isn't real-time collaboration—you'll need to refresh to see updates—but it eliminates the hassle of converting files to Google formats.

You can also comment on PDFs, images, videos, audio, or other files. Sharing permissions apply: view-only access means you can read comments but not add or share.

Prefer full editing? Convert Office files in Google Workspace anytime. Right-click an Office file in Drive, select Open with > Docs, Sheets, or Slides. For direct editing, install the Office Editing for Docs, Sheets & Slides Chrome extension—it supports DOC, XLS, and PPT in compatibility mode.
