I get an exception deep in Aspose when opening the attached password-protected xlsx file. Excel appears to open it without a problem. The problem showed up when a potential customer submitted the file. I’ve done light editing of the file to remove sensitive information and changed the password - the symptoms when trying to open are still the same.
After an initial test, I am able to reproduce the issue as you have mentioned. I have logged your issue with an id: CELLSNET-27998. We will look into your issue soon.
We have fixed this issue. Please download: Aspose.Cells for .NET v188.8.131.52.
Thanks for the quick response! I’ll check it out today.
