When I convert this XLS to XLSX, Aspose produce a broken XLSX that I cannot open in Excel.
The original XLS file opens successfully in Excel.
Using - aspose-cells-20.4.jar
The code that I am using is:
com.aspose.cells.LoadOptions loadOptions = new com.aspose.cells.LoadOptions(com.aspose.cells.FileFormatType.EXCEL_97_TO_2003);
com.aspose.cells.Workbook workbook = new com.aspose.cells.Workbook(inputPath, loadOptions);
The original XLS file and broken XLSX file are attached.
