I am a self taught Excel/VBA Business Systems Analyst who has built numerous Excel cost modelling, planning, forecasting and scheduling systems over the past 10 years. I would now like to develop a web-site to promote some of these Systems. Where possible, I would like to develop the site using Excel? I have seen a website (zoho.com zoho sheet) that enables users to utilise certain excel functions and VBA on-line. Can you please advise if there are any addins or products available that provide this type of functionality?
