You could generate a data URI, and let the user save the link. However, IE8 has very limited support for data URIs. There is a 32 KB limit, and it's not allowed to be used with a href.

Also, you still need to find a actual XLSX JS library... But it is possible.

It has been done successfully by Ed Spencer. This project is using an EXT DataGrid as the source of the data, but I'm sure you could adapt it pretty easily.

As Javascript has no file I/O, it's not going to be easy for your users to download. However, this kind of work is perfectly suited for a simple PHP script, which could generate your XSLX and save to your server dynamically.

As for allowing the user to save a file from JS I recommend FileSaver.js https://github.com/eligrey/FileSaver.js/
