can't export excel to pdf.

If the regular “Export to PDF” feature in Excel Online isn’t working, you can still create a PDF using your browser’s Print function. This works well in most cases.

On Desktop (Chrome, Edge, etc.):

1. Open your Excel file in Excel Online (in the browser).
2. Click on File > Print > Print (don’t choose “Download as PDF” if that’s giving errors).
3. A print preview will load – wait until it finishes loading.
4. The browser's print dialog will open.
5. In the print dialog:
6. Set the Destination / Printer to: "Save as PDF".
7. Adjust settings like pages, layout, scaling, etc., if needed.
8. Click Save and choose where to save the PDF on your computer.

On iPhone / iPad (iOS):

If you’re using Excel Online in Safari or Chrome:

1. Tap the Share icon (a square with an arrow pointing up).
2. Choose Print.
3. In the print preview, zoom in on the preview with two fingers – this opens the document as a PDF.
4. Then tap Share again to:

• Save to Files
• Send via email
• Or open in another app (e.g., Books or Drive)

If that still doesn't work:

There might be a problem with:

• your browser's cache
• the specific Excel workbook
• or a temporary issue with Excel Online

If needed, you can also try:

• opening the file in Google Sheets and exporting to PDF from there
• or downloading it and opening it in Excel desktop
