I'm not familiar with any financial models, but I've seen a lot excel stuff for analyzing data. so here are my 2cts: When I worked for a x-Ray tube company, they used excel to prepare data for the tube controller. I took 1-2 hours for every tube and only 2 people were able to do this. My first task was to improve this situation. I used ruby for this, although they wanted me to do this in VBA ;-) With my final version it was possible to create the data 1) within 5 min per tube 2) automatically from the command line 3) independent of the number of data sets (excel strongly depends on the number of rows or columns of input data). The drawbacks: 1) people could not longer use Excel - I'm not kidding, this IS a real disadvantage, because (esp.) non-programmers tend to use excel for everything. That's why it's a lot easier to give your software away, when you've written it in Excel (or calc). People are simply familiar with it. 2) no gui - my gui was an editor with the config file opened. Anything else (like a cool gui) will keep you from the problem (or I am just not familiar with writing guis). I think ruby is a really good choice for doing these things - implementation could take a while, but you'll get a lot back: Most important might be Unit-testing (I'm sure there are thousands of buggy excel lists in the banks out there - hey might be the REAL reason for the crisis ;-). As long as you do not want to change anything excel is ok, because it simply runs. Keep in mind, who should use your software - programs are most useful when used properly. regards ralf
