I have tried every combination I can think of yet I still get _TypeError: fs is undefined. Attached is the HTML file with embedded script.

Am I missing something??

index.txt

I get this as well - any news on this?

I'm having issues with this as well. Looking through the code, it appears that js-xlsx relies on Node's fs module. I'm not sure how that works (I'm fairly new to all of this), but I'm working on figuring out how to either pull in the fs module as a dependency or create my own wrapper that uses javascript's FileReader underneath (worst case scenario)

Also running into issues with this. If anyone figures out a good workaround, I'd love to know (and will likewise comment here I figure something out)

Look at #285

You can't use fs or XLSX.readFile in the browser. Use XLSX.read. If you need specific examples, the demo http://oss.sheetjs.com/js-xlsx/ source is in the gh-pages branch of the repo. index.html uses HTML5 File API and ajax.html uses XMLHttpRequest
