Invalid file format


We’re running the new 3.3 version and receive an invalid file format exception when we try to open a spreadsheet in any version other than excel 2003. Any ideas?
Thanks, Donta


Hi Donta,

I think you saved your file as “Microsoft Excel97-2003 & 5.0/95 Workbook”. You can see it in the “Save as” dialog. Aspose.Excel supports Excel97-2003 and this dual stream file is not supported.

If you do want to save your template file as previous version, please use the corresponding Excel to open and save it as “Microsoft Office Excel Workbook”.
