Describe the bug
Hi,Benji.
I found that if I open an existing excel file, save it and close it, and then use excel to open the file, I will get an error.


If I change mode from createoropen to create, there will be no errors. The same thing happens in C#

alike

The problem has not been resolved, and this error appears when you open a workbook created in excel. Workbooks created with NPOI do not have this problem.
