You may be interested in this
http://www.programmingforums.org/thread15823.html which shows Excel
solving Dijkstra's Algorithm.

Excel is probably Turing complete (opinions differ) if you exclude the
notion of infinite sets.

If you consider a web site that collects user details, generates an
insurance quote and takes payment, then my initial assessment (I've not
built it yet) is Excel has the required features, including
authentication, logging, cookies etc. You would need a web server to
launch each Excel 'program', and you would need a module that converts
formatted Excel pages into HTML. Some functions like calling web
services and HTML formatting might practically have to be implemented as
non-Excel code (eg VBA or Ruby) but as these would require only simple
configuration they could be viewed as extensions to the inbuilt
functions and would not require programming ability on the part of the
user.

The issue (sometimes called the Turing Tarpit) is that Excel is a
programming alnguage but without many of the sophistications you see in
the likes of Ruby, and therefore may be unnecessarily awkward to program
in.

Nevertheless I think it is instructive. If you can imagine solving
practical problems in Excel then you should be able to solve the same
problems in the more accepted functional languages without being tempted
to slip back into imperative habits.

I guess my little bit of tinkering with this leads me to ask "Why should
I have to instruct the computer how to navigate data structures and code
my own error capturing? Why can't I just define what I want to see, and
then look at whether it turns out as I expected?"
