There are two ways to apply conditional formatting to blank cells in Excel:

1. Choose Format only cells that contain within the Conditional Formatting box.

2. Choose Use a formula to determine which cells to format within the Conditional Formatting box.

The following examples show how to use each method with the following dataset in Excel that shows the points scored by various basketball players during different games:

To ensure that the formula works correctly, be sure to use the cell in the top left corner of your range of cells in the ISBLANK() function.

In this example, we used cell A2 since it represented the cell in the top left corner of our range.
