RE: Does SheetJs work in netsuite serverside script
I think SheetJS is not AMD-compatible by default, I had to
shim (https://requirejs.org/docs/api.html#config-shim) it in with require config file corresponding to the
@NAmdConfig JSDoc tag.
I have gotten it to work serverside in the past though if you just wanted some encouragement to invest time into that route 🙂
