Question

我正在尝试从API提取一些Excel文件并对其进行解析，但是，我一直在阅读ReadableStream。这是我要获取的：

const fetchData = async () => {
  const response = await fetch('https://cors-anywhere.herokuapp.com/http://ukrstat.gov.ua/operativ/operativ2013/fin/kp_reg/kp_reg_u/xls_u/kp_reg_u_2018.xlsx');
  console.log(response);
};

fetchData();

我正在使用React，所以很高兴获得一些建议，以XLSX继续处理此信息

这是我解决此特定问题的方法：

const fetchData = async () => {
  const response = await fetch('https://cors-anywhere.herokuapp.com/http://ukrstat.gov.ua/operativ/operativ2013/fin/kp_reg/kp_reg_u/xls_u/kp_reg_u_2018.xlsx');
  return response;
};

const parseExcel = async () => {
  const stream = await fetchData();
  const arrayBuffer = await stream.arrayBuffer();
  const data = new Uint8Array(arrayBuffer);
  const arr = new Array();
  for (let i = 0; i != data.length; ++i) arr[i] = String.fromCharCode(data[i]);
  const bstr = arr.join('');
  const workbook = XLSX.read(bstr, { type: 'binary' });
  const sheet = workbook.Sheets;
  const sheetName = Object.keys(sheet)[0];
  const json = XLSX.utils.sheet_to_json(workbook.Sheets[sheetName], { header: 1 });
  console.log(json);
};

parseExcel();

如何将可读流转换为Excel文件对象？
