What is the purpose of "Conditional Formatting" in Excel?

The purpose of "Conditional Formatting" in Excel is to highlight certain cells based on specified criteria. This feature allows users to apply formatting changes such as colors, font styles, and fill patterns to cells that meet certain conditions or criteria. For example, you might use conditional formatting to change the background color of cells that contain values above a certain threshold, making it easier to visually analyze data trends and identify important information at a glance.

By applying this tool, users can effectively emphasize critical data points within large datasets, enhance readability, and facilitate quick decision-making based on visual cues without modifying the underlying data. This dynamic visual representation of data is an important feature for anyone working with data analysis in Excel.
