I have been working on excel without a problem for a while now. But this evening I tried to go to 'file' to save the document and then convert to 'pdf' but I was not getting the drop down menu I usually get. All I got was the program freezing and a message saying not responding. Can you please help.

Hi,

Did you get an error message Excel is not responding? Problems with Excel crashing or hanging can be caused by several things.

We could try to do following mothods:

Method 1: Verify/install the latest updates
Method 2: Start Excel in safe mode
Method 3: Investigate possible issues with add-ins
Method 4: Check whether your antivirus software is up to date or is conflicting with Excel
Method 5: Make sure that Excel is not being used by another process
Method 6: Check whether your file is being generated by a third party
Method 7: Test by using a new local or network profile
Method 8: Perform a selective startup to determine whether a program, process, or service conflicts with Excel
Method 9: Repair or reinstall your Office program
