Using Aspose.Cells API
Aspose.Cells provides a class, Workbook that represents a Microsoft Excel file. The Workbook class contains a WorksheetCollection that allows access to each worksheet in the Excel file.
A worksheet is represented by the Worksheet class. The class provides a wide range of properties and methods for managing a worksheet and other objects. Each worksheet consists of a Cells collection. To create subtotals in a worksheet, use the Cells class' subtotal method. Provide appropriate values for the parameters of the method to get the result you want.
The example below shows how to create subtotals in the first worksheet of the template file (Book1.xls) using Aspose.Cells API.
When the code is executed, a worksheet with subtotals is created.
