Answer 1

There is a Microsoft Office Javascript API now: https://docs.microsoft.com/en-us/office/dev/add-ins/develop/understanding-the-javascript-api-for-office
Another thing to do is save your excel file as .csv and process that in javascript. (You can open the csv file in your code editor, the file format is really easy)

Answer 2

Martin Taylor Yeah or you can also do a `<input type="file">`, "upload" a file, and then manipulate that with `FileReader`. But you can't read directly from the hard drive yeah.

But there are probably easier tutorials out there. I don't know any tutorials though, I'm sure google will find lots.
