Convert Excel to.net .ascx control

I have a spreadsheet with 3 tabs, I would like each of these tabs turned into a vb.net ascx controls. On the LoanPricing tab the blue fields are your input and on the two growth tabs, the fields with the white background are your input. It would be nice to use some client side JavaScript to perform proper formatting for numbers, percent sighs, etc.. Calculations should take place server side using an update button. Please be smart about naming fields, don't name fields C9, name it "ExpectedROA1" for example.
