Aspose.Cells - Calculate Sub Totals

You can automatically create subtotals for any repeating values in a spreadsheet. Aspose.Cells provides API features that help you add subtotals to spreadsheets programmatically.

Java

//Instantiate a new workbook
Workbook workbook = new Workbook("book1.xls");

//Get the Cells collection in the first worksheet
Cells cells = workbook.getWorksheets().get(0).getCells();

//Create a CellArea, i.e., B3:C19
CellArea ca = new CellArea();
ca.StartRow = 2;
ca.StartColumn = 1;
ca.EndRow = 18;
ca.EndColumn = 2;

//Apply subtotal, the consolidation function is Sum and it will be applied to
//Second column (C) in the list
cells.subtotal(ca, 0, ConsolidationFunction.SUM, new int[] { 1 });

//Save the Excel file
workbook.save(dataDir + "AsposeTotal.xls");
