Office.js Apps: Excel Cannot Find The Home.html File

I'm trying to learn how to write Office.js apps. I did use the example given here. Manifest file, QuarterlySalesReportManifest.xml, I did change the value of SourceLocation element

Solution 1:

While the add-in's manifest can be hosted on a file share (and thus served through the "file" protocol), the add-in itself has to be served through http/https. I'd recommend either hosting the file locally through IIS during development or using Visual Studio for developing your add-in.
