AutoFit Rows for Rendering with JavaScript via C++
Contents

]
Generally, when you want to display all the text in a cell, you can auto-fit the row in Normal view with 100% zoom in Microsoft Excel. This allows the text to be fully visible in Normal view, and even when you print or save the file as a PDF, the text will be displayed correctly.
However, in some cases, auto-fitting the row works fine in Normal view, but when you switch to print view or save the file as a PDF, the text gets clipped. Please check the source file Book1.xlsx and screenshots.
If you want to prevent text from being clipped in the saved PDF file, you can auto-fit the row with the AutoFitterOptions.forRendering option.

return;
}
const file = fileInput.files[0];
const arrayBuffer = await file.arrayBuffer();
// Init workbook instance from uploaded file.
const workbook = new Workbook(new Uint8Array(arrayBuffer));
// Set autofit options for rendering.
const autoFitterOptions = new AutoFitterOptions();
autoFitterOptions.forRendering = true;
// Autofit rows with options on first worksheet.
const worksheet = workbook.worksheets.get(0);
worksheet.autoFitRows(autoFitterOptions);
// Save to pdf.
const outputData = workbook.save(SaveFormat.Pdf);
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;">Operation completed successfully! Click the download link to get the PDF file.</p>';
});

Now, the text is not clipped in the output PDF file.
