What is the purpose of the Subtotal command in a worksheet?

The Subtotal command serves a specific function within a worksheet: it allows users to calculate and display automatic totals for grouped data. When data is organized into categories or groups, the Subtotal command can efficiently generate aggregate calculations such as sums, averages, counts, or other statistical metrics for each group. This feature not only simplifies the task of handling large datasets but also makes it easier to analyze summarized information quickly.

For instance, if you have a sales report organized by product categories, using the Subtotal command enables you to see the total sales for each category without manually calculating these sums. This automated approach enhances productivity and maintains data integrity, as it reduces the risk of human error associated with manual calculations.

While other options such as formatting numbers as currency, removing duplicates, or changing the layout of data are useful features, they do not fulfill the specific function of aggregating totals for grouped data as the Subtotal command does. Each of those tasks addresses different aspects of data management and analysis, but the core purpose of the Subtotal command is distinct in its focus on providing summary calculations for organization and clarity.
