As already mentioned before, dropdowns are incredibly useful when you are making a presentation. You can basically take a whole spreadsheet’s worth of data and turn them into just one clickable format that you then just have to scroll up and down for. When coupled with some of the other useful functions in Google Sheet, you can see why this is such an attractive prospect. You will see exactly how useful dropdowns are in the next section, where you will learn how to use this function. For now, just imagine how chaotic a presentation will be if you are using dozens or even hundreds of columns and rows in a single report, which you will then need to present in front of your superiors, teachers, or other authority figures. If you have to keep scrolling up and down or left and right just to find the right data that you need, this would take way too much time. Even if it is just for a few seconds, it would not look good when the people you are trying to impress are being made to wait for you to find the thing that you yourself worked on.  For that reason alone, you can already see how useful dropdowns can be.
