Generate PDF and Excel usgin Javascript(Client side)

Is there a client side Javascript framework similar to jasper report in Java.My requirement is to generate both PDF and Excel at client side(browser) without doing it at server side. I have found that there are javascript libraries like JsPDF and PDFkit to generate PDF and different library for generate Excel which make the development effort much harder.I want some thing exactly similar to what is done by jasper report.Also if it can be added using NPM without manual importing to the code and use it then it is much suitable for my requirement. Anybody give some help on this it is highly appreciate.Thanx.
