Excel Drop Down List Allows Invalid Entries

Drop down lists make it easier to enter data on a worksheet, and they help ensure that only valid items will be entered in the cell.

Counting in Excel

The most popular function in Excel is SUM, based on my experience. That’s probably the first function you learned how to use, and in the old days, it was the only function that you could insert with the appropriately named AutoSum button.

Sometimes we overlook how much counting we have to do every day too. Here are a few scenarios that you might encounter at work (or should I say “en-count-er”?):

Fortunately, the problem is easy to fix, if you know how, and if you have the patience to do lots of clicking.
