How do I generate excel reports with rich formatting including charts with a ASP.Net application?
As per http://support.microsoft.com/kb/257757 server-side automation of office is not advisable and also our admin does not allow installation of office on the server
Customer is not ready to spend a lot on 3rd party components
A must requirement is to retain the formatting used by the end user already and also use ONLY excel 2003.
Thanks
Update: We are using ExcelXmlWriter from http://www.carlosag.net/Tools/ExcelXmlWriter/Generator.aspx as it was the most fit.
You can use for example this Excel XML library for rich formatting, but unfortunately there are no charts in there.
Without any third party component and Office automation (which is really not recommended on servers) you have basically the two options as JasonS proposed.
