Create Pivot Table

It is possible to use Aspose.Cells for Node.js via C++ to add pivot tables to spreadsheets programmatically.

Pivot Table Object Model

Aspose.Cells for Node.js via C++ provides a special set of classes that are used to create and control pivot tables. These classes are used to create and set PivotTable objects, the building blocks of a pivot table. The objects are:

• PivotField represents a field in a PivotTable.
• PivotFieldCollection represents a collection of all the PivotField objects in the PivotTable.
• PivotTable represents a PivotTable on a worksheet.
• PivotTableCollection represents a collection of all the PivotTable objects on a worksheet.

Creating a Simple Pivot Table Using Aspose.Cells

1. Add data to a worksheet using the Cell object’s putValue method. This data will be used as the pivot table’s data source.
2. Add a pivot table to the worksheet by calling the PivotTables collection’s add method, which is encapsulated in the Worksheet object.
3. Access the new PivotTable object from the PivotTables collection by passing the PivotTable index.
4. Use any of the PivotTable objects (explained above) to manage the pivot table.

After executing the example code, a pivot table is added to the worksheet.

const AsposeCells = require("aspose.cells.node");

//Instantiating a Workbook object
var workbook = new AsposeCells.Workbook();

//Obtaining the reference of the newly added worksheet
var sheetIndex = workbook.getWorksheets().add();
var sheet = workbook.getWorksheets().get(sheetIndex);
var cells = sheet.getCells();

//Setting the value to the cells
var cell = cells.get("A1");
cell.setValue("Sport");
cell = cells.get("B1");
cell.setValue("Quarter");
cell = cells.get("C1");
cell.setValue("Sales");

cell = cells.get("A2");
cell.setValue("Golf");
cell = cells.get("A3");
cell.setValue("Golf");
cell = cells.get("A4");
cell.setValue("Tennis");
cell = cells.get("A5");
cell.setValue("Tennis");
cell = cells.get("A6");
cell.setValue("Tennis");
cell = cells.get("A7");
cell.setValue("Tennis");
cell = cells.get("A8");
cell.setValue("Golf");

cell = cells.get("B2");
cell.setValue("Qtr3");
cell = cells.get("B3");
cell.setValue("Qtr4");
cell = cells.get("B4");
cell.setValue("Qtr3");
cell = cells.get("B5");
cell.setValue("Qtr4");
cell = cells.get("B6");
cell.setValue("Qtr3");
cell = cells.get("B7");
cell.setValue("Qtr4");
cell = cells.get("B8");
cell.setValue("Qtr3");

cell = cells.get("C2");
cell.setValue(1500);
cell = cells.get("C3");
cell.setValue(2000);
cell = cells.get("C4");
cell.setValue(600);
cell = cells.get("C5");
cell.setValue(1500);
cell = cells.get("C6");
cell.setValue(4070);
cell = cells.get("C7");
cell.setValue(5000);
cell = cells.get("C8");
cell.setValue(6430);

var pivotTables = sheet.getPivotTables();

//Adding a PivotTable to the worksheet
var index = pivotTables.add("=A1:C8", "E3", "PivotTable2");

//Accessing the instance of the newly added PivotTable
var pivotTable = pivotTables.get(index);

//Unshowing grand totals for rows.
pivotTable.setRowGrand(false);

//Dragging the first field to the row area.
pivotTable.addFieldToArea(AsposeCells.PivotFieldType.Row, 0);

//Dragging the second field to the column area.
pivotTable.addFieldToArea(AsposeCells.PivotFieldType.Column, 1);

//Dragging the third field to the data area.
pivotTable.addFieldToArea(AsposeCells.PivotFieldType.Data, 2);

//Saving the Excel file
workbook.save("CreatePivotTable_out.xlsx");

When assigning a range of cells as the data source, the range must go from top left to bottom right. For example, “A1:C3” is valid but “C3:A1” is not.
