A family of Microsoft spreadsheet software with tools for analyzing, charting, and communicating data.
Hi Neal,
Thanks for reaching out. I understand how frustrating it can be when a feature you’ve relied on suddenly starts working differently. I'm here to help!
First, the most common reason Excel only saves one sheet as a PDF is that the export option defaults to the active sheet. To fix this, go to File > Save As or Export > Create PDF/XPS, click Options, and choose Entire Workbook instead of Active Sheet.
Second, make sure all sheets have the same page setup like paper size, orientation, and print quality. If these differ Excel may split them into separate PDFs.
Third, if you only need specific sheets, you can Ctrl or Shift‑select those tabs before exporting, then choose the appropriate option in the PDF settings.
Last, if it still doesn’t work, it could be a bug or driver issue. Alternatives include using Adobe Acrobat, Power Automate, or a VBA macro to combine sheets into one PDF.
I hope you find this information helpful. Please let me know if you have any further questions If the answer is helpful, please click "Accept Answer".
