coudl you send me a sample code - How to open an existing excel file in a browser
Do you need some grid like control/environment where a client can see, open/save or manipulate Excel files in WYSIWYG (visual) manner on the web. If this is the case, you may make use of our control that supports these features, i.e.
Aspose.Cells.GridWeb ---> it is a web based grid control provided by Aspose.Cells for .NET, see the demos and docs:
Note: The control is independent controls and bundled together in the Aspose.Cells for .NET package, the control will also be installed when you install Aspose.Cells for .NET using its MSI installer.
Also, our more popular Aspose.Cells component is just a library which does not have any interface, the component is used for all types of Excel spreadsheets manipulation and management, it supports almost all the Excel features (97-2010). So, alternatively, if you need to open the generated/re-saved file by Aspose.Cells (Aspose.Cells.dll) on the fly into MS Excel, you may make use of System.Diagnostics.Process.Start(fileName) .NET API for windows applications. Also, you may use the concerned Workbook.Save() overload which contains Response object as its parameter to response the generated Excel workbook to retrieve it on the client system/browser in his MS Excel (see the document for reference: http://www.aspose.com/docs/display/cellsnet/Saving+Files).
Also, another way is create images for the Excel workbook/worksheets and you may display it on the web page using Aspose.Cells' Worksheet-to-Image feature, see the topic for your reference:
