Trying to load a xlsm file in the workbook using -->
Workbook.Load(fileStream);
Getting an exception - Invalid or unrecognized file format. (Parameter 'stream')
This is a dot net standard 2.0 project. The same line of code works fine in a .net framework 4.6 project.
Any ideas on what can be the issue ?
I even tried a one liner code Workbook.Load(fileStream); within a .net framework 4.6.1 app and a dot net core 3.1 app but the dot net core failed to fetch the xlsm file.
Hello,
Thank you for posting in our community.
In order to provide you with better and more accurate support, I will need some clarifications regarding your environment. Is your query about Ignite UI for MVC's Excel Engine on .NET Core version 2.0 or 3.1?
If this is not the case can you please share more details regarding your scenario? This information is going to be highly appreciated and helpful for determining how to proceed further.
Looking forward to hearing from you.
