Hi there,
We're in the process of evaluating Aspose.Grid and Aspose.Cells however we're not off to a very good start. I have tried a simple import of an existing Excel spreadsheet in to the component using a very simple C# app and version 2.0.1 of the component and it makes quite a mess of rendering it.
I have attached the xls file in question for your development gurus to have a play with and hopefully improve the product overall. Unfortunately I don't think we will be using Aspose.Grid for our spreadsheet rendering requirements however, on a brighter note, Aspose.Cells appears to do everything that we require of it at this point with regard to handling spreadsheets behind the scenes.
