Save Specified Worksheets to PDF with C++

By default, Aspose.Cells saves all visible worksheets in a workbook to a PDF file. With the PdfSaveOptions.GetSheetSet() option, you can save specified worksheets to a PDF file. For example, you can save the active worksheet to PDF, save all worksheets (both visible and hidden) to PDF, or save custom multiple worksheets to PDF.

Save Active Worksheet to PDF

If you want to export only the active sheet to PDF, you can achieve this by passing SheetSet.GetActive() to the PdfSaveOptions.GetSheetSet() option.

The sheet Sheet2 is the active sheet of the source file sheetset-example.xlsx.

#include <iostream>
#include "Aspose.Cells.h"
using namespace Aspose::Cells;

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

    // For complete examples and data files, please go to https://github.com/aspose-cells/Aspose.Cells-for-C

    // Open the template Excel file
    Workbook workbook(u"sheetset-example.xlsx");

    // Set active sheet to output
    PdfSaveOptions pdfSaveOptions;
    pdfSaveOptions.SetSheetSet(SheetSet::GetActive());

    // Save the PDF file with PdfSaveOptions
    workbook.Save(u"output.pdf", pdfSaveOptions);

    std::cout << "PDF file saved successfully!" << std::endl;

    Aspose::Cells::Cleanup();
}

Save All Worksheets to PDF

SheetSet.GetVisible() indicates visible sheets in a workbook, and SheetSet.GetAll() indicates all sheets, including both visible sheets and hidden/invisible sheets in a workbook. If you want to export all sheets to PDF, you can simply pass SheetSet.GetAll() to the PdfSaveOptions.GetSheetSet() option.

The source file sheetset-example.xlsx contains all four sheets, with hidden sheet Sheet3.

#include <iostream>
#include "Aspose.Cells.h"
#include "Aspose.Cells/PdfSaveOptions.h"
#include "Aspose.Cells/SheetSet.h"

using namespace Aspose::Cells;

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

    // For complete examples and data files, please go to https://github.com/aspose-cells/Aspose.Cells-for-C

    // Open the template Excel file
    Workbook workbook(u"sheetset-example.xlsx");

    // Set all sheets to output
    PdfSaveOptions pdfSaveOptions;
    pdfSaveOptions.SetSheetSet(SheetSet::GetAll());

    // Save the PDF file with PdfSaveOptions
    workbook.Save(u"output.pdf", pdfSaveOptions);

    std::cout << "PDF file generated successfully!" << std::endl;

    Aspose::Cells::Cleanup();
}

Save Specified Worksheets to PDF

If you want to export desired/custom multiple sheets to PDF, you can achieve this by passing multiple sheet indices to the PdfSaveOptions.GetSheetSet() option.

#include <iostream>
#include "Aspose.Cells.h"
#include "Aspose.Cells/PdfSaveOptions.h"
#include "Aspose.Cells/SheetSet.h"

using namespace Aspose::Cells;

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

    // For complete examples and data files, please go to https://github.com/aspose-cells/Aspose.Cells-for-C

    // Open the template Excel file
    U16String inputFilePath(u"sheetset-example.xlsx");
    Workbook workbook(inputFilePath);

    // Set custom multiple sheets (Sheet1, Sheet3) to output
    Vector<int32_t> sheetIndexes = {0, 2};
    SheetSet sheetSet(sheetIndexes);
    
    // Initialize PDF save options
    PdfSaveOptions pdfSaveOptions;
    pdfSaveOptions.SetSheetSet(sheetSet);

    // Save the PDF file with PdfSaveOptions
    U16String outputFilePath(u"output.pdf");
    workbook.Save(outputFilePath, pdfSaveOptions);

    std::cout << "Excel file saved as PDF successfully!" << std::endl;

    Aspose::Cells::Cleanup();
    return 0;
}

Reorder Worksheets to PDF

If you want to reorder sheets (e.g., in reverse order) to PDF without modifying the source file, you can achieve this by passing reordered sheet indices to the PdfSaveOptions.GetSheetSet() option.

#include <iostream>
#include "Aspose.Cells.h"
using namespace Aspose::Cells;

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

    // For complete examples and data files, please go to https://github.com/aspose-cells/Aspose.Cells-for-C

    // Open the template Excel file
    Workbook workbook(u"sheetset-example.xlsx");

    // Reorder sheets (Sheet1, Sheet2, Sheet3, Sheet4) to (Sheet4, Sheet3, Sheet2, Sheet1)
    Vector<int32_t> sheetIndexes = { 3, 2, 1, 0 };
    SheetSet sheetSet(sheetIndexes);

    // Create PdfSaveOptions and assign the sheet set
    PdfSaveOptions pdfSaveOptions;
    pdfSaveOptions.SetSheetSet(sheetSet);

    // Save the PDF file with PdfSaveOptions
    workbook.Save(u"output.pdf", pdfSaveOptions);

    std::cout << "PDF saved successfully!" << std::endl;

    Aspose::Cells::Cleanup();
}

If your spreadsheet contains formulas, it is best to call Workbook.CalculateFormula() just before rendering the spreadsheet to PDF format. Doing so will ensure that the formula‑dependent values are recalculated, and the correct values are rendered in the PDF.
