I recently updated my Aspose.Cells version within my project and now workbooks that have ActiveX controls within them get corrupted. When the Excel file opens up I get a warning about “unreadable content”. Example attached.
Thanks for the file and sample code.
I have tested your issue and found the issue. The output XSLM file is corrupt as you pointed out.
string filePath = @"E:\test2\activex\Book1.xlsm";
Workbook workbook = new Workbook(filePath);
