How does conditional formatting enhance data visibility in Excel?

Conditional formatting enhances data visibility in Excel by applying color or style based on specific conditions. This feature allows users to set rules that change the appearance of cells when certain criteria are met. For instance, a user may choose to highlight all values above a certain number in green and those below in red. This visual differentiation helps in quickly identifying important data trends, outliers, or specific values at a glance, leading to a more intuitive understanding of the data set and aiding in decision-making processes.

This method of visual enhancement can make large datasets much easier to analyze by drawing attention to key areas without the need for extensive manual sorting or filtering. The ability to apply this formatting dynamically means that whenever the underlying data changes, the formatting automatically updates, ensuring that the most relevant information is always highlighted.
