Use conditional formatting to make cells automatically change color based on data.
Conditional formatting allows you to change a cell's color based on the information within the cell. For example, if you want to flag certain numbers that are above average or in the top 10% of the data in your spreadsheet, you can do that. If you want to color code commonalities between different rows in Excel, you can do that. This will help you quickly see information that is important to you.
To get started, highlight the group of cells you want to use conditional formatting on. Then, choose "Conditional Formatting" from the Home menu and select your logic from the dropdown. (You can also create your own rule if you want something different.) A window will pop up that prompts you to provide more information about your formatting rule. Select "OK" when you're done, and you should see your results automatically appear.
