Hi Eric A spreadsheet is an indexed / tabular structure which doesn't map well to Haskell's built-in way of defining data - algebraic types - which are trees via sums and products.
Wolfram Kahl has a paper on modelling tables in Haskell "Compositional Syntax and Semantics of Tables" which might be interesting / useful: tables look like they have strong similarities to spreadsheets and the implementation is included in the appendix. Unfortunately the code is very complicated - I say this intending no criticism or judgement of Wolfram's work, just that it takes a lot of type system power to get over the representation mismatch between trees and tables.
