You can highlight the row containing the minimum or maximum value in Excel using conditional formatting. Here's how:

Highlighting Minimum Value:

1. Select the data range: Choose the range of cells containing the values you want to analyze (e.g., A1:C10).
2. Go to Conditional Formatting: Navigate to the "Home" tab and click on "Conditional Formatting" in the "Styles" group.
3. New Rule: Select "New Rule" from the dropdown menu.
4. "Use a formula to determine which cells to format": Choose this option in the "New Formatting Rule" window.
5. Formula for Minimum: Enter the following formula in the "Format values where this formula is true" box:

```excel
=A1=MIN($A$1:$C$1) (Assuming your data starts in row 1)
```

Explanation of the formula:

- `A1`: This refers to the value in the current cell you're applying the rule to (adjust the cell reference if your data starts in a different column).
- `MIN($A$1:$C$1)`: This part finds the minimum value within the entire selected data range (A1:C1 in this example). Using absolute references ($A$1:$C$1) ensures the range stays fixed even if you copy the rule to other cells.
- The `=` sign compares the value in the current cell (A1) with the minimum value in the entire range.

6. Formatting: Click on the "Format" button and choose the desired highlighting options (e.g., fill color, font color) for the row containing the minimum value.
7. Click OK: Click "OK" on both the "Format Cells" and "New Formatting Rule" windows.

Highlighting Maximum Value:

Repeat the steps above, but replace the formula in step 5 with:

```excel
=A1=MAX($A$1:$C$1)
```

This formula will identify the row containing the maximum value within your data range.

By following these steps, you can easily highlight the row containing the minimum or maximum value in your Excel dataset, making it visually distinct for quick identification.
