How to add data validation list in excel using javascript

> I am creating and downloading excel file with data that I have gotten in JSON format. Now I want to add status column in last and provide list data validation there with three specified value "rejected","sleected" and "on-hold"

 downloadTableData(data, headers) {
  this.dataToDownload = "";
  let dataSourceLength = data.length;
  let rowData = '';
  for (let i = 0; i < dataSourceLength; i++) {
    let line = '';
    for (let key in data[i]) {
      if (line != '') {
        line = line + ','
      }
      line = line + data[i][key];
    }
    rowData = rowData + line + "\r\n";
  }

  // as of now; but based on api data, row data and column dat ashould be done
  this.dataToDownload = this.dataToDownload + headers.join(',') + "\r\n" + rowData;

  if (this.dataToDownload.split('\n').length - 1 >= 1) {
    // const fileName = 'reports-' + new Date();
    const fileName ='Upload_template.xlsx';
    let anchor = document.createElement('a');
    anchor.href = URL.createObjectURL(new Blob([this.dataToDownload], { type: 'text/csv' }));
    anchor.download = fileName + '.csv';
    // anchor.download = fileName;
    // start download
    anchor.click();
  }

}
