I'm looking for a viable alternative to Excel automation to manipulate, read and create excel files in an ASP.NET website context.
I'm aware of a couple of component builders that support these scenario's:
- Aspose Cells,
- softartisans OfficeWriter
But these all have one thing in common, they're very expensive.
I'd prefer a solution that supports both Office 2003 file formats and Office 2007 file formats, but a good solution that only supports either, is no problem for me.
I've also found a few links to System.IO.Packaging, but I haven't been able to find a good tutorial that shows how to create and manipulate excel files, other than through complex XML manipulation.
