Let’s go through a step-by-step process of how to use the Subtotal feature in Excel effectively.

Before adding subtotals, ensure your data is organized into a table format. Make sure your dataset has headers, as these will help you categorize the data for subtotaling.

Step 2: Select Your Data

• Ensure that you include all relevant columns that you would like to analyze.

Step 3: Access the Subtotal Feature

Example Scenario:

Imagine you have a sales dataset categorized by region. Here’s how you can apply the subtotal:

<table> <tr> <th>Region</th> <th>Sales</th> </tr> <tr> <td>North</td> <td>1000</td> </tr> <tr> <td>North</td> <td>1500</td> </tr> <tr> <td>South</td> <td>1200</td> </tr> <tr> <td>South</td> <td>1800</td> </tr> </table>

Applying subtotals for the "Sales" column will show the total sales for each region.
