Coding from Excel to Web

Hello, I have five very simple Excel programs that I offer with a digital product. The trouble is that a number of purchases do not have Excel on their computer, they have very early versions of Excel such as '95' or they may have works or something similar and as such, our Excel programs won't function. I was after some guidance firstly on the options I have. I understand I could get the small programs developed into like a Windows based program or possibly the easiest option may be to run them off the internet. I am not exactly sure how this would be done however I welcome any feedback. I have attached a sample application titled 'Betting Exchange Calculator'. There are three sheets to this application. We would envisage there to be ongoing work after the initial project for the right applicant. A number of the other applications are more involved using 'solver'. Many thanks, Matt ## Deliverables 1) Complete and fully-functional working program(s) in executable form as well as complete source code of all work done. 2) Deliverables must be in ready-to-run condition, as follows (depending on the nature of the deliverables): a) For web sites or other server-side deliverables intended to only ever exist in one place in the Buyer's environment--Deliverables must be installed by the Seller in ready-to-run condition in the Buyer's environment. b) For all others including desktop software or software the buyer intends to distribute: A software installation package that will install the software in ready-to-run condition on the platform(s) specified in this bid request. 3) All deliverables will be considered "work made for hire" under U.S. Copyright law.
