一、导出word文档

参考文章https://blog.csdn.net/qq_53722480/article/details/130017092
1、使用到的包如下：

"docxtemplater": "^3.42.4",
"file-saver": "^2.0.5",
"jszip-utils": "^0.1.0",
"pizzip": "^3.1.4",

2、页面中使用，注意：demo.docx模板文件放在public目录下

<script setup>
import JSZipUtils from "jszip-utils";
import JSZip from "pizzip";
import Docxtemplater from "docxtemplater";
import { saveAs } from "file-saver";

//导出方法
const exportDoc=()=>{
  // 读取并获得模板文件的二进制内容"
  JSZipUtils.getBinaryContent(`${"/demo"}.docx`, (error, content)=> {
    // 抛出异常
    if (error) {throw error;}
    // 创建一个PizZip实例，内容为模板的内容
    const zip = new JSZip(content);
    // 创建并加载docxtemplater实例对象
    const doc = new Docxtemplater().loadZip(zip);
    // 设置模板变量的值
    doc.setData({
      isTable: [{ index:1,name:"测试数据",id:'fdfd'},{index:2,name:'小如',id:'fdgfrdgr'}], // 文档中循环数据
    });
    try {
      // 用模板变量的值替换所有模板变量
      doc.render();
    } catch (error) {
      // 抛出异常
      const e = {
        message: error.message,
        name: error.name,
        stack: error.stack,
        properties: error.properties,
      };
      console.log(JSON.stringify({ error: e }));
      throw error;
    }
    // 生成一个代表docxtemplater对象的zip文件（不是一个真实的文件，而是在内存中的表示）
    const out = doc.getZip().generate({
      type: "blob",
      mimeType:
          "application/vnd.openxmlformats-officedocument.wordprocessingml.document",
    });
    // 将目标文件对象保存为目标类型的文件，并命名
    saveAs(out, "模板文件.docx");
  });
}
</script>

3、demo.docx文件内容如下
在这里插入图片描述
4、下载后的模板文件.docx如下

二、导出excel文档

1、使用到的包如下

"xlsx": "^0.18.5"

2、界面中导出excel

// 前端导出excle的方法
import { aoaToSheetXlsx } from '@/utils/ExportExcel'

function exportExcles() {
  let header = [   //表头
    {label:'名称', prop:'name' }, 
    {label:'类型', prop:'type' },
    {label:'状态', prop:'status' }
  ]
  let data=[		//导出的数据
    {name: '测试', type: '1', status: '0'},
    {name: '测试', type: '1', status: '0'},
    {name: '测试', type: '1', status: '0'},
    {name: '测试', type: '1', status: '0'},
    {name: '测试', type: '1', status: '0'},
  ]
  aoaToSheetXlsx({
    header,
    data: data,
    filename: 'excel导出名字',   //excel文件名
  })
}

3、ExportExcel.js如下：

import {utils, writeFile} from 'xlsx';

const DEF_FILE_NAME = 'new-excel';
export function jsonToSheetXlsx({
  data,
  header,
  filename = DEF_FILE_NAME,
  json2sheetOpts = {},
  write2excelOpts = { bookType: 'xlsx' },
}) {
  const tHeader = header.map(v => {
    return (v.label)
  })
  const filterVal = header.map(v => {
    return (v.prop)
  })
  const newData = formatJson(filterVal, data)
  const arrData = [...newData];
  if (tHeader) {
    arrData.unshift(tHeader);
    json2sheetOpts.skipHeader = true;
  }
  const worksheet = utils.json_to_sheet(arrData, json2sheetOpts);
  /* add worksheet to workbook */
  const workbook = {
    SheetNames: [filename],
    Sheets: {
      [filename]: worksheet,
    },
  };
  /* output format determined by filename */
  writeFile(workbook, filename, write2excelOpts);
  /* at this point, out.xlsb will have been downloaded */
}

export function aoaToSheetXlsx({
  data,
  header,
  filename = DEF_FILE_NAME,
  write2excelOpts = { bookType: 'xlsx' },
}) {
  const tHeader = header.map(v => {
    return (v.label)
  })
  const filterVal = header.map(v => {
    return (v.prop)
  })
  const newData = formatJson(filterVal, data)
  const arrData = [...newData];
  if (tHeader) {
    arrData.unshift(tHeader);
  }
  const worksheet = utils.aoa_to_sheet(arrData);
  const name = filename + '.xlsx'
  /* add worksheet to workbook */
  const workbook = {
    SheetNames: [filename],
    Sheets: {
      [filename]: worksheet,
    },
  };
  /* output format determined by filename */
  writeFile(workbook, name, write2excelOpts);
  /* at this point, out.xlsb will have been downloaded */
}

function formatJson(filterVal, jsonData) {
  return jsonData.map(v => filterVal.map(j => {
    if (j === 'timestamp') {
      return parseTime(v[j])
    } else {
      return v[j]
    }
  }))
}
