Hi, If you like, I can prepare a 3min video for you, showing you a Web Questionary that we created for a Financial Service Company, questions appears with fading effect, it was done in C# ASP.NET Core 2.0 + javascript + Bootstrap CSS which by the latest benchmarks is currently the fastest web framework out there.
We are Microsoft Registered Partners, we are in the middle of two big projects in excess of 7.5k, but based on the fact that you already have the Excel workflow done, I think we can pull this at the same time.
Thanks!
Felice
