Issue while converting XLS file to XLSX using Aspose.Cells for Java

Hi,



With Excel 2008 on Mac I can open a .xls file without issues.

When writing the same file to .xlsx I see the above error message.

Additionally it says ‘The file might have been damaged or modified from its original format.’.



The way I write the file is like this:



workbook.save(outputStream, FileFormatType.EXCEL2000);



or



workbook.save(outputStream, FileFormatType.EXCEL2007);



I attached the files.

Hi,

Thanks for your posting.

This problem has been fixed in our latest version Aspose Cells for Java (Latest Version). Please download.
