I’m having trouble opening an Excel 2003 workbook. Aspose.Cells errors with “Object reference is null”. Would you mind taking a look?
I’m using Cells version 18.104.22.168.
The error occurs at:
designer.Workbook.Open(UserDirectory + “/” + FileName);
Thanks for providing us the template file.
We found the issue and will figure it out.
Please try this fix.
