Failed to save xlsb to xlsx

Hi,

I used the following code snippet to load the XLSB file and save it as an XLSX file with Aspose.Cells .Net 20.11.

var options = new Aspose.Cells.LoadOptions(LoadFormat.Xlsb);
                using (var doc = new Workbook(@"sample.xlsb", options))
                    doc.Save(@"sample_out.xlsx", SaveFormat.Xlsx);
                Console.WriteLine("Done");

And the sample is here sample.zip (4.4 MB)
But the output file is broken when opening with MS Excel, so can you investigate the problem?

Thanks.
