When I import the package, I keep getting the following:

Module not found: Can't resolve 'fs'

Hey @oluwaseunladeinde I'm having the same issue. From what I can gather, fs is the file system module for Node.js. It lets you access files on your device. Node is meant to be run in the back-end, so I think we're seeing this error from attempting to use node-xlsx in the browser, where it's not meant to be used and has no file system to access.

Have a look at SheetJS if you're after something for Excel parsing and manipulation in the browser :)
