I would be very surprised to see Javascript in a browser writing
something in another application (Excel).
Without a feature of the system of user's computer I imagine you can't
do what you want.
Perhaps an applet in Java ?
You can try to put (copy via JS) your datas in a html table, then to
save this new page and to ask Excel to open it ?
yeah you can't do this because the access methods only come with the
user having office on their machine of course, so if they don't have
office you are stuck. Also of course this would be heavy security
restrictions surrounding anything like this.
You can easily interact with a webpage <--> MS Office using COM inside
IE, but that's it, plus of course you can have a macro inside the
office document, which if allowed to run would do a similar thing.
Here's an example of a webpage generating data, opening excel and
drawing a graph. I think I got it from the MS website here?
http://support.microsoft.com/kb/234774 once:
just save as html, open from the local file system (or you will have
to allow a few security warnings)
This stuff is great if you are generating data from a database for an
end user on a intranet where you can control the end usrs machine via
group policy, obviously the webpage could make use of data input by
the user, or data from the server / database / parsed from an upload
from the user / web service / feed etc...
