By default, Aspose.Cells saves all visible worksheets in a workbook to a PDF file. With the PdfSaveOptions.sheetSet 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 a custom selection of 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.active to the PdfSaveOptions.sheetSet option.
The sheet Sheet2 is the active sheet of the source file sheetset-example.xlsx.

const workbook = new Workbook(new Uint8Array(arrayBuffer));
// Prepare PdfSaveOptions and set the active sheet set
const pdfSaveOptions = new PdfSaveOptions();
pdfSaveOptions.sheetSet = SheetSet.active;
// Save workbook to PDF using PdfSaveOptions
const outputData = workbook.save(SaveFormat.Pdf, pdfSaveOptions);
const blob = new Blob([outputData], { type: 'application/pdf' });
const downloadLink = document.getElementById('downloadLink');
downloadLink.href = URL.createObjectURL(blob);

downloadLink.textContent = 'Download PDF File';
resultDiv.innerHTML = '<p style="color: green;">Conversion completed successfully! Click the download link to get the PDF.</p>';
});

Save All Worksheets to PDF
SheetSet.visible indicates visible sheets in a workbook, and SheetSet.all indicates all sheets, including both visible and hidden sheets, in a workbook. If you want to export all sheets to PDF, you can simply pass SheetSet.all to the PdfSaveOptions.sheetSet option.
The source file sheetset-example.xlsx contains four sheets, with the hidden sheet Sheet3.

Save Specified Worksheets to PDF
If you want to export specific custom multiple sheets to PDF, you can achieve this by passing an array of sheet indices to the PdfSaveOptions.sheetSet option.

return;

const file = fileInput.files[0];
const arrayBuffer = await file.arrayBuffer();
// Open the Excel file through the file input
const workbook = new Workbook(new Uint8Array(arrayBuffer));
// Set custom multiple sheets (Sheet1, Sheet3) for output
const sheetSet = new SheetSet([0, 2]);
const pdfSaveOptions = new PdfSaveOptions();
pdfSaveOptions.sheetSet = sheetSet;
// Save the PDF file with PdfSaveOptions
const outputData = workbook.save(SaveFormat.Pdf, pdfSaveOptions);
const blob = new Blob([outputData], { type: 'application/pdf' });
const downloadLink = document.getElementById('downloadLink');
downloadLink.href = URL.createObjectURL(blob);

downloadLink.textContent = 'Download PDF File';
document.getElementById('result').innerHTML = '<p style="color: green;">PDF created successfully! Click the download link to get the PDF.</p>';
});

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

}).then(() => {

document.getElementById('runExample').addEventListener('click', async () => {
const fileInput = document.getElementById('fileInput');
if (!fileInput.files.length) {
document.getElementById('result').innerHTML = '<p style="color: red;">Please select an Excel file.</p>';
return;
}
const file = fileInput.files[0];
const arrayBuffer = await file.arrayBuffer();
// Instantiate a Workbook object by opening the Excel file from the file input
const workbook = new Workbook(new Uint8Array(arrayBuffer));
// Reorder sheets (Sheet1, Sheet2, Sheet3, Sheet4) to (Sheet4, Sheet3, Sheet2, Sheet1)
const sheetSet = new SheetSet([3, 2, 1, 0]);
const pdfSaveOptions = new PdfSaveOptions();
pdfSaveOptions.sheetSet = sheetSet;
// Save the PDF file with PdfSaveOptions
const outputData = workbook.save(SaveFormat.Pdf, pdfSaveOptions);
const blob = new Blob([outputData], { type: 'application/pdf' });
const downloadLink = document.getElementById('downloadLink');
downloadLink.href = URL.createObjectURL(blob);
downloadLink.download = 'output.pdf';
downloadLink.style.display = 'block';
downloadLink.textContent = 'Download PDF File';
document.getElementById('result').innerHTML = '<p style="color: green;">PDF created successfully! Click the download link to get the PDF file.</p>';

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