Hi,<?xml:namespace prefix = o ns = "urn:schemas-microsoft-com:office:office" />
Thank you for considering Aspose.
Aspose.Cells is a pure library rather than a visual GUI control. It is used to read and write native excel files with all types of sophisticated formatting, formula calculations, charts creation and more. The files generated by Aspose.Cells component can be viewed in Excel Viewer or MS Excel. The component is capable of sending the output file to client browser or client's MS Excel for viewing in web application or you may use System.Diagnostics.Process.Start(excelfile) method to open the file into browser in desktop application.
Also, Workbook.Open() method is used to open the file for processing by Aspose.Cells, this method is not for opening the excel file for viewing.
Thank You & Best Regards,
