I like to color data entry cells, so they’re easy to spot on an Excel worksheet. If you know that you should type a value in every blue cell, it’s quicker, and safer, to fill in a worksheet.
Recently, I was asked how to color a specific number of data entry cells, based on a number that someone selected from a drop down list. So, instead of manually coloring the data entry cells, I used conditional formatting to color them.
In the screen shot below, 3 was selected in cell C2, so 3 data entry cells are blue, in cells C5:C7.
