使用axios通过oss的url获取.xlsx文件流，处理后得到json格式数据：

安装xlsx：

npm install xlsx

javascript 复制代码

import axios from "axios";
import * as XLSX from "xlsx";

//#region xlsx(oss) to json
async function getFileStream(url) {
  const response = await axios.get(url, { responseType: "blob" });
  return response.data;
}

async function convertFileStreamToWorkbook(fileStream) {
  const reader = new FileReader();
  return new Promise((resolve, reject) => {
    reader.onload = (event) => {
      try {
        const workbook = XLSX.read(event.target.result, { type: "binary" });
        resolve(workbook);
      } catch (error) {
        reject(error);
      }
    };
    reader.onerror = (error) => {
      reject(error);
    };
    reader.readAsBinaryString(fileStream);
  });
}

async function convertWorkbookToJson(workbook) {
  const sheetName = workbook.SheetNames[0]; // 获取第一个工作表的名称
  const worksheet = workbook.Sheets[sheetName]; // 获取第一个工作表对象
  const jsonData = XLSX.utils.sheet_to_json(worksheet); // 将工作表对象转换为JSON对象
  return jsonData;
}

export async function xlsxToJson(OSSUrl) {
  const fileStream = await getFileStream(OSSUrl);
  const workbook = await convertFileStreamToWorkbook(fileStream);
  const jsonData = await convertWorkbookToJson(workbook);
  return jsonData;
}
//#endregion

使用：

javascript 复制代码

    (async () => {
      const json = await xlsxToJson(
        "https://xxxxxxx.xlsx" // ossUrl
      );
      setAuthorDatas([...json]);
    })();
