Excel in VSTO
 

Hello all,
I have a very general question.
I automatically generate many Excel charts daily (using VBA) with data from
Oracle databases. The system is noninteractive, but the users can view these
charts in any web browser from any platform.
Now I want to introduce interactivity using ASP or ASP.NT, where the users
could create their own charts based on say time period. I know that
VisualStudio Tools for Office server-side solution is possible. My question
is: does this solution require Office to run on the client PC? We have some
PCs that run Linux so all they have is a browser.
Thanks for any help, Milos.
