After an initial test, I observed the issue as you mentioned. I found an issue with the output XLSB file in XLS to XLSB Conversion. The output file is corrupt and MS Excel displays warning messages when opening the output file into MS Excel 2010 manually.
e.g Sample code:
Workbook workbook = new Workbook(“e:\test2\POLIS-BN_Polis.xls”); workbook.save(“e:\test2\out1.xlsb”, new XlsbSaveOptions(SaveFormat.XLSB));
