Sorry in my previous communication I was speaking about the versions 22.6 and 22.5.
Please try using the new version: Aspose.Cells for .NET v22.6.1, it will fix all your issues. And, you won’t find the corrupted file issue anymore. Let us know if you still find the issue.
Thanks a lot. I have downloaded the last release and I will proceed to the test to evaluate this version.
