I'm working on a MS CRM 2016 solution which requires to access to an Excel Online document. It doesn't metter if using JS or C# with a plugin. The problem is that I do not find a clear documentation/example about how to just open this XLSX whch stays on the cloud. Can you please suggest me any "starting point"?
What I have tried:
I have visited the Microsoft official documentationi for Office 365 and in particular the Excel REST Api. The problem is that, as usual, their doc seems to let you force to use some techs that I can't (the sample app is a Windows UWP).
