Absolutely! Highlighting top or bottom values in a range is a breeze using Conditional Formatting in Excel. Here's how you can achieve this:

1. Select the range: Choose the cells containing the data you want to analyze (where you want to highlight top or bottom values).

2. Conditional Formatting: Navigate to the "Home" tab on the Excel ribbon. In the "Styles" group, click the dropdown arrow next to "Conditional Formatting."

3. Top/Bottom Rules: Within the Conditional Formatting options, choose "Top/Bottom Rules."

4. Highlight Top or Bottom: A new window will appear. Here, you can decide whether to highlight the top or bottom values. You can choose options like "Top 10 Items," "Bottom 10%," or enter a specific number of values to highlight.

5. Formatting: Select the formatting style you want to apply to the highlighted cells. You can choose font color, fill color, cell borders, or a combination of these.

6. OK: Click "OK" to apply the conditional formatting rule.

Now, your spreadsheet will automatically highlight the top or bottom values (depending on your chosen criteria) within the selected range. This will update dynamically as you change or add data to your range.
