Nicole Ahmed (ID: 000000a5eb87142e) Voted 5 ★ - Updated 11/08/2023 Excellent extension and a very responsive developer. I've tried lots of the office extensions on chrome and most are rubbish, some are malicious. This extension is innovative and so useful. The peek window to preview files before fully opening them is excellent, The pop out window is great because you resize the window and have it open alongside your other work. This doesn't have editing capabilities, just viewing. But is very useful for viewing documents conveniently. Highly recommend
