Gorilla Sheet

Su*****

This is the GREATEST extension I've ever used. The toughest change for me when transitioning from finance to tech was the more Google Sheets-heavy usage in tech - the native shortcuts and functionality in Google Sheets is pretty limited, and there is no way to easily drill-down several layers in complex formulas / models. Gorilla Sheet solves this exact problem. For anyone who's looking to be as efficient in Google Sheets and save 100s of hours, Gorilla Sheet is an awesome extension.
