首先，我的开发环境是：vue3+vue-cli+element
安装dependencies运行依赖项 xlsx

npm install xlsx --save

使用xlsx读取excel文件内容
组件代码

<template>
  <el-upload class="upload-demo" action='' drag :auto-upload="false" :on-change="uploadChange" :limit="1">
    <i class="el-icon-upload"></i>
    <div class="el-upload__text">将文件拖到此处，或<em>点击上传</em></div>
  </el-upload>
</template>

<script>
import xlsx from 'xlsx';
import {readFile} from '../plugins/readFile.js'; //下文有该文件代码

export default {
  name: 'upload',
  methods:{
    async uploadChange(file){
      let dataBinary = await readFile(file.raw)
      let workBook = xlsx.read(dataBinary, {type: 'binary', cellDates: true})
      let workSheet = workBook.Sheets[workBook.SheetNames[0]]
      const data = xlsx.utils.sheet_to_json(workSheet)
      console.log(data)
    }
  }
}
</script>

readFIle.js

export const readFile = (file) => {
return new Promise(resolve => {
let reader = new FileReader()
reader.readAsBinaryString(file)
reader.onload = ev => {
resolve(ev.target.result)
}
})
}

输出结果
