Add Filter in Pivot Table

Possible Usage Scenarios

When you create a pivot table with known data and want to filter the pivot table, you need to learn and use filter. It can help you filter out the data you want effectively. By using the Aspose.Cells for Node.js via C++ API, you can add filter on field values in Pivot Tables.

Add Filter in Pivot Table Using Aspose.Cells for Node.js via C++

Please see the following sample code. It sets the data and creates a PivotTable based on it. Then add a filter on the row field of the pivot table. Finally, it saves the workbook in output XLSX format. After executing the example code, a pivot table with top10 filter is added to the worksheet.

Sample Code

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

//Instantiating an Workbook object
var workbook = new AsposeCells.Workbook();
//Obtaining the reference of the newly added worksheet
var ws = workbook.getWorksheets().get(0);
var cells = ws.getCells();
//Setting the value to the cells
var cell = cells.get("A1");
cell.putValue("Fruit");
cell = cells.get("B1");
cell.putValue("Count");
cell = cells.get("A2");
cell.putValue("Apple");
cell = cells.get("A3");
cell.putValue("Mango");
cell = cells.get("A4");
cell.putValue("Blackberry");
cell = cells.get("A5");
cell.putValue("Cherry");
cell = cells.get("A6");
cell.putValue("Guava");
cell = cells.get("A7");
cell.putValue("Carambola");
cell = cells.get("A8");
cell.putValue("Banana");
cell = cells.get("B2");
cell.putValue(5);
cell = cells.get("B3");
cell.putValue(3);
cell = cells.get("B4");
cell.putValue(6);
cell = cells.get("B5");
cell.putValue(4);
cell = cells.get("B6");
cell.putValue(5);
cell = cells.get("B7");
cell.putValue(2);
cell = cells.get("B8");
cell.putValue(20);

//Adding a PivotTable to the worksheet
var i = ws.getPivotTables().add("=A1:B8", "D10", "PivotTable1");
//Accessing the instance of the newly added PivotTable
var pivotTable = ws.getPivotTables().get(i);
pivotTable.addFieldToArea(AsposeCells.PivotFieldType.Row, 0);
pivotTable.addFieldToArea(AsposeCells.PivotFieldType.Data, "Count");

pivotTable.getDataFields().get(0).setFunction(AsposeCells.ConsolidationFunction.Sum);

var field = pivotTable.getRowFields().get(0);
field.setIsAutoSort(true);
field.setIsAscendSort(false);
field.setAutoSortField(0);
//Add top10 filter
var index = pivotTable.getPivotFilters().add(0, AsposeCells.PivotFilterType.Count);
var filter = pivotTable.getPivotFilters().get(index);
filter.getAutoFilter().filterTop10(0, True, False, 5);
pivotTable.refreshData();
pivotTable.calculateData();
workbook.save("out.xlsx");
