Re: [Haskell] Making a spreadsheet with Haskell

You could take a look at Vital http://www.cs.kent.ac.uk/projects/vital/

From the web page:

Vital is a visual programming environment based on Haskell, a contemporary functional programming language. It is particularly intended for supporting the open-ended, incremental style of development often preferred by end users (engineers, scientists, analysts, etc.). It may also be useful for teaching Haskell. Simon
