How to create and download xlsx on the client?

Can you please tell me if this code can be simplified, or is it done correctly:

import React, { Fragment } from 'react';
import xlsx from 'node-xlsx';
import download from 'downloadjs';

function TableDownload({ data }) {
  return (
    <Fragment>
      <button onClick={_ => {
        const qwerty = [[1, 2, 3], ['a', 'b', 'c']];
        let buffer = xlsx.build([{ name: "mySheetName", data: qwerty }]).toString('base64');
        download(atob(buffer), 'data.xlsx', { type: "application/vnd.openxmlformats-officedocument.spreadsheetml.sheet" });
      }}>12345</button>
    </Fragment>
  );
}

export default TableDownload;

Everything happens on the client side: a file is created, which is then downloaded, without reloading the page. The data is first converted to the "base64" string and then decoded. Everything works, but I want the code to be "in line with tradition", and there was nothing superfluous in it.

Regards.
