I'm trying to develop a Office Add-In for Excel (n00b).
I have managed to do some things (creating tables and taking input and so on) when using Office.context.
But now I want to go into the different cells and all examples seems to run a method called Run on a object called Excel. (https://github.com/OfficeDev/office-js-docs/blob/master/excel/excel-add-ins-programming-overview.md)
However when trying to use Excel it's undefined. I am running Excel 2013. Can it be that I need to use 2016?
