Getting warning message while opening excel file pragmatically created


in my project (.NET C#) i am creating excel file on fly without using office.interop. But after downloading the file when user tries to open the file, user getting an warning message saying “the source of the file is not a trusted one, do you want to open the file any way ?” if user clicks on yes then file gets opened.

My questions is by using Aspose can we avoid this warning ?

Thanks & Regards,
