Insert Slicer

Possible Usage Scenarios

A slicer is used to filter data quickly. It can be used to filter data both in a table or pivot table. Microsoft Excel allows you to create slicer by selecting a table or pivot table and then clicking the Insert > Slicer. Aspose.Cells for Node.js via C++ also allows you to create slicer using the Worksheet.getSlicers().add() method.

Create Slicer to a Pivot Table

Please see the following sample code. It loads the sample Excel file that contains the pivot table. It then creates the slicer based on the first base pivot field. Finally, it saves the workbook in output XLSX and output XLSB format. The following screenshot shows the slicer created by Aspose.Cells for Node.js via C++ in the output Excel file.

Sample Code

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


// Load sample Excel file containing pivot table.
var wb = new AsposeCells.Workbook("sampleCreateSlicerToPivotTable.xlsx");

// Access first worksheet.
var ws = wb.getWorksheets().get(0);

// Access first pivot table inside the worksheet.
var pt = ws.getPivotTables().get(0);

// Add slicer relating to pivot table with first base field at cell B22.
var idx = ws.getSlicers().add(pt, "B22", pt.getBaseFields().get(0));

// Access the newly added slicer from slicer collection.
var slicer = ws.getSlicers().get(idx);

// Save the workbook in output XLSX format.
wb.save("outputCreateSlicerToPivotTable.xlsx", AsposeCells.SaveFormat.Xlsx);

// Save the workbook in output XLSB format.
wb.save("outputCreateSlicerToPivotTable.xlsb", AsposeCells.SaveFormat.Xlsb);

Create Slicer to Excel Table

Please see the following sample code. It loads the sample Excel file that contains a table. It then creates the slicer based on the first column. Finally, it saves the workbook in output XLSX format.

Sample Code

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

// Load sample Excel file containing a table.
var workbook = new AsposeCells.Workbook("sampleCreateSlicerToExcelTable.xlsx");

// Access first worksheet.
var worksheet = workbook.getWorksheets().get(0);

// Access first table inside the worksheet.
var table = worksheet.getListObjects().get(0);

// Add slicer
var idx = worksheet.getSlicers().add(table, 0, "H5");

// Save the workbook in output XLSX format.
workbook.save("outputCreateSlicerToExcelTable.xlsx", AsposeCells.SaveFormat.Xlsx);
