如何使用sheetJS和node读取上传文件的工作表数据？

npm install xlsx

const xlsx = require('xlsx');

function readUploadedFile(file) {
  const workbook = xlsx.readFile(file.path);
  const worksheet = workbook.Sheets[workbook.SheetNames[0]];
  const jsonData = xlsx.utils.sheet_to_json(worksheet, { header: 1 });
  return jsonData;
}

const express = require('express');
const multer = require('multer');
const app = express();
const upload = multer({ dest: 'uploads/' });

app.post('/upload', upload.single('file'), (req, res) => {
  const file = req.file;
  const data = readUploadedFile(file);
  // 处理读取到的工作表数据
  res.send(data);
});
