Introduction to Conditional Formatting in Excel

Conditional Formatting in Excel is like the traffic lights of a dataset. It guides you where to pay attention. It is a great tool that allows you to automatically apply a format to a cell based on certain criteria. This could be anything from a simple color fill to data bars and color scales, helping you visualize data at a glance.

Understanding the difference between blank and non-blank cells in Excel is important for accurate data analysis. While both types of cells might appear empty, only truly blank cells contain no data whatsoever. Cells that may look blank could hold invisible characters, like spaces or formulas returning empty strings. By differentiating them correctly, you can make your Excel workbooks more reliable and error-proof.

Blank Cells Not Highlighted

Sometimes, the blank cells may not get highlighted after applying the rule. It can be because:

• The order of conditional formatting is interfering. If any existing rule affecting the same cell is above, Excel will apply that rule and ignore the rule below.

• The formula is incorrect. The syntax or the referenced cell may be wrong.
• Cells that seem empty but contain spaces.
