211720 Excel to web conversion

I have an Excel spreadsheet that contains macros (data analysis>regression). It has 1 worksheet. It is a simple price estimator using customer entered data and returning a response. Excel conversion programs do not support Macros, so cant be used. The prgramming language does not matter. All I wish is for the worksheet(s) to be converted to a suitable web based application (posted as a free online service). The models and formulae should not be easily accessed by users. If you have experience in regression models and Excel macros and can convert to a web application, please apply. I can provide a number of links to source code to perform regression calculation.
