I don't know if this tool could help with this...but if you want check
out www.kdcalc.com...This lets you develop your code in Excel and then
KDCalc will convert the excel spreadsheet into either a java or .Net
implementation for execution not using Excel. May not help with this
but may be useful in the future. There's a free/no registration
download of the tool to test with. I've used it a bit and it's saved me
a lot of time reprogramming.
