var name = f.name;
const reader = new FileReader();
reader.onload = (evt) => { // evt = on_file_select event
    /* Parse data */
    const bstr = evt.target.result;
    const wb = XLSX.read(bstr, {type:'binary'});
    /* Get first worksheet */
    const wsname = wb.SheetNames[0];
    const ws = wb.Sheets[wsname];
