Losing Text Boxes when converting Excel spreadsheet to PDF

[USMailBob]

This is a problem that just started happening today. I have Adobe Acrobate XI. For years I have been successfully converting price quotes that are created in Microsoft Excel (Office 365 Business - fully updated) to PDF files. The Excel quote spreadsheet contains a couple of text boxes. All of a sudden, when converting the Excel file to PDF, the text boxes are missing from the newly created PDF file. I am able to print the Excel file just fine, with the text boxes included. This is happening with multiple quote spreadsheets, so it does not appear to be isolated to just one of them. I have Windows 10 Pro Version 1803. This is driving me nuts, so if anyone has a recommendation for fixing this I'd appreciate it!

Can you tell us what technique you are using to convert from Excel to PDF?  There are a few wyas, and some can yield better results than others.

My best,

Yes - this is only happening when I am bundling one of my Excel spreadsheet quotes along with a PDF file line drawing using the "Combine Files Into PDF" function. Quite often in my business we are sending quotes, drawings, product info, etc. to customers, so we like to bundle everything into a single PDF file.

Subsequent to me leaving my original message above I did discover that if I just save the spreadsheet quote using the "Save As" function in Excel, the resulting PDF file is just fine. So it only appears to be not working correctly when combining files. Very weird. I've been using this same method successfully for YEARS with no issues. 

Is there some setting in Acrobat that could have been changed somehow?

Thanks for your help.
