Can not load file

I get “This file’s format is not supported or you don’t specify a correct format” error when I try to open attached file with the following code :

Aspose.Cells.Workbook wb = new Aspose.Cells.Workbook(@“C:\TEMP\test5\synergy.xls”);
Hi Huseyin,

Thanks for your posting and using Aspose.Cells.

This file is actually in a very old format which is not supported by Aspose.Cells APIs. If you open it in Excel application and save it with Save-As menu, you will notice that Excel will show you its format i.e Microsoft Excel 5.0/95 Workbook (*.xls). Please note, Aspose.Cells APIs support BIFF8 or greater formats (Excel 97 - Excel 2010/2013), so you cannot read/write the Excel 95 or earlier file formats.

As a workaround, you may try the following steps to work with this file while using Aspose.Cells APIs.
  • Open your template file into MS Excel (e.g..,Ms Excel 2003 or 2007/2010).
  • Save the file As "Microsoft Office Excel Workbook".
Now you can use Aspose.Cells to open/manipulate the file for your requirements, it will work fine.

Thank you for your quick response and the information suplied.
