Our web application is built on VS 2003 and its consuming Aspose.Excel version 2.6.0.0 to generate dataset and its working fine till now.
But I found error when i tried to process .xlsx file (excel 2007) at
excel.Open(memoryStream)
Its giving an error of NullReferenceException,
Please let me know the workaround of it. As well as if latest version is required than please let me know the version and price detail of that.

Hi Prashant,

Thank you for considering Aspose.

Well, as you are using a very old version of Aspose.Cells, so you may face such issue with Excel 2007 format files. We will recommend you to try our latest Aspose.Cells version by downloading from the following location:
