Hello - I just wanted to add details on how I ended up fixing this. Thanks again to everyone who replied.    I don't know if I would recommend this as the best way to fix this, but it is what ended up fixing the issue for me.   One of the things I saw to try was running the built-in Repair utility on Microsoft Office. But when I ran the repair, it ended up completely uninstalling Office from my PC. So I ended up having to reinstall Microsoft Office on my PC - and after that, PROC IMPORT with Excel files worked again.  ... View more

No Office upgrade in a long time. But I think you are right - this might be something to do with the underlying utility that SAS uses to communicate with Office files.

Thank you to all 3 of you for the quick replies! The crash is occurring both when I try to read Excel files from a network drive, and from my C: drive.    I did not try the csv, but I did try DBMS=XLSX instead of DBMS=Excel, and XLSX worked.    I will open a tech support ticket. I don't want to have to go rip out code in many of our production programs, especially since several of us on my team use those programs, not just me. And I don't necessarily want to replace code that worked fine for years, and suddenly stopped working on my pc. I have pasted my original code, that is crashing SAS, below.   At least I know I can use xlsx if I can't get anything else working.     PROC IMPORT OUT= WEBCASEXLS_202122 DATAFILE= "L:\BOUNCE\Data\CASEALL_Download_202122.xlsx" DBMS= EXCEL REPLACE; RANGE="CASEALL$"; GETNAMES=YES; MIXED=NO; SCANTEXT=YES; USEDATE=YES; SCANTIME=YES; RUN; ...
