Spreadsheet programs are used daily by millions of people for
tasks ranging from neatly organizing a list of addresses to complex economical sim-
ulations or analysis of biological data sets. Spreadsheet programs are easy to learn
and convenient to use because they have a clear visual data model (tabular) and a
simple efficient computation model (functional and side effect free).
Spreadsheet programs are usually not held in high regard by professional soft-
ware developers [19]. However, their implementation involves a large number of
non-trivial design considerations and time-space tradeoffs. Moreover, the basic
spreadsheet model can be extended, improved or otherwise experimented with in
many ways, both to test new technology and to provide new functionality in a con-
text that could make a difference to a large number of users.
Yet there does not seem to be a coherently designed, reasonably efficient open
source spreadsheet implementation that is a suitable platform for experiments. Ex-
isting open source spreadsheet implementations such as Gnumeric and OpenOffice
are rather complex, written in unmanaged languages such as C and C++, and the
documentation of their internals is sparse. Commercial spreadsheet implementa-
tions such as Microsoft Excel neither expose their internals through their source
