Microsoft Javascript Add-In: read/write to Excel, Access

I am trying to create a Microsoft Word Add in. I would like the javascript Add in to have the ability to read and write to Microsoft Access and Microsoft Excel files. This is trivial with VBA, but I do not want to divide up the user experience between my Javascript add in and a VBA button in the original Word document. I would like to be able to read and write from the Javascript add in somehow.

I know I have access to things like Word.run(function (context) {..... from the docs, but example functions have nothing to do with accessing other documents.

What is the right way to access other Microsoft documents from a Javascript add in to read and write?

Thanks.

By "other Microsoft documents" I'll assume you are talking about any related files the user has stored on their PC. But these JavaScript for Office add-ins are essentially just web pages running in an embedded browser, and applications running in a browser are sandboxed and just don't have access to the local computer (without installing client helper applications).

So your app will need to prompt the user to upload a file to your web server where you can interact with the file using a relevant API (which would be a completely different topic). Or you can use web-based APIs to interact with web-based file systems (OneDrive/Graph, Dropbox, etc.).
