I have several financial applications that are programmed in excel and work very well. I've gone through several programmers who say that converting from excel to an online app like PHP is easy to do but then they come back and say they need the math formulas for the excel functions.
Someone suggested to pass the variables the user enters online to an excel spreadsheet and then pass results back to the online app.
Does that make sense and what would the hardware setup be and how to get that to work
Any other recommendations to speed up getting excel applications up and functioning online. Sometimes there are some visual basic programming within the excel spreadsheet
TIA for your help
