We do Financial analysis of different Insurance options and tax consequences of those options using excel. Then we have a programmer convert the excel spreadsheets we work this up on to a program we then provide to members of our group who are NOT proficient with excel but if we hand them a program that says `fill in the clients age in this box' it's what they want and are comfortable with. It also protects the formulas we create for security purposes this way.
Are there any tools to convert excel spreadsheets in this manner?
I noticed some that convert excel to web pages but am not sure how well they work.
We've been using the .NET framework and I'd appreciate comments on what other options we'd have.

TIA for your help
