I got a Excel file from my client which I can open it in Excel 2010 with a warning message, but not able to load it using Aspose.Cells 7.0.3.
I guess this file is saved in mhtml format since I can open it using text editor.
So I tried to use LoadOptions to load it using HTML format and it is also failed.
I think either I did something wrong, or Aspose.Cells doesn't support this format.
I attached a sample file for your investigation. Please help to identify this issue.
