Setting Pivot Table Option - For Empty Cells Show with C++

You can set different pivot table options using Aspose.Cells. One such option is “For empty cells show”. By setting this option, all empty cells in a pivot table are displayed as a specified string.

Setting Pivot Table Option in Microsoft Excel

To find and set this option in Microsoft Excel:

1. Select a pivot table and right-click.
2. Select PivotTable Options.
3. Select the Layout & Format tab.
4. Select the For empty cells show option and specify a string.

Setting Pivot Table Option Using Aspose.Cells

Aspose.Cells provides the PivotTable.GetDisplayNullString() and PivotTable.GetNullString() properties for setting the “For empty cells show” pivot table option.

#include <iostream>
#include "Aspose.Cells.h"

using namespace Aspose::Cells;

int main()
{
    Aspose::Cells::Startup();

    // Source directory path
    U16String srcDir(u"..\\Data\\01_SourceDirectory\\");

    // Output directory path
    U16String outDir(u"..\\Data\\02_OutputDirectory\\");

    // Path of input excel file
    U16String inputFilePath = srcDir + u"input.xlsx";

    // Path of output excel file
    U16String outputFilePath = outDir + u"output_out.xlsx";

    // Create workbook
    Workbook wb(inputFilePath);

    // Get the first worksheet
    WorksheetCollection sheets = wb.GetWorksheets();
    Worksheet sheet = sheets.Get(0);

    // Get the first pivot table
    PivotTableCollection pivotTables = sheet.GetPivotTables();
    PivotTable pt = pivotTables.Get(0);

    // Indicating if or not display the empty cell value
    pt.SetDisplayNullString(true);

    // Indicating the null string
    pt.SetNullString(u"null");

    // Calculate pivot table data
    pt.CalculateData();

    // Set refresh data on opening file to false
    pt.SetRefreshDataOnOpeningFile(false);

    // Save the workbook
    wb.Save(outputFilePath);

    std::cout << "Pivot table settings applied successfully!" << std::endl;

    Aspose::Cells::Cleanup();
}
