原生方法（简单）

https://blog.csdn.net/qq_41579327/article/details/125088468?spm=1011.2415.3001.5331

纯前端方法

vue、vite、webpack环境多可用

安装

npm i exceljs

使用

import ExcelJS from 'exceljs'/*** data: [{tital1:'', tital2:'', tital3:'', tital4:'', tital5:'', tital6:'', tital7:'', tital8:'', tital9:'', tital10:'', tital11:''}...]**/
const exportExcel = async (data) => {const workbook = new ExcelJS.Workbook()const worksheet = workbook.addWorksheet('sheet1', {properties: { defaultRowHeight: 36, defaultColWidth: 20 },// 打印配置pageSetup: {horizontalCentered: true,verticalCentered: true,paperSize: 9,orientation: 'landscape',scale: 81,margins: {left: 0.25,right: 0.25,top: 0.75,bottom: 0.75,header: 0.3,footer: 0.3}}})worksheet.mergeCells('A1:K1') // 合并单元格const a1 = worksheet.getCell('A1') // 获取A1单元格a1.value = '抽查表' // 设置内容a1.alignment = { vertical: 'top', horizontal: 'center' } // 设置内容居中a1.font = { size: 20, bold: true } // 设置字体worksheet.getRow(1).height = 40 // 设置行高const a2 = worksheet.getCell('A2')a2.value = '抽查日期：'a2.alignment = { vertical: 'middle', horizontal: 'left' }a2.font = { size: 14, bold: true }worksheet.mergeCells('J2:K2')const j2 = worksheet.getCell('J2')j2.value = `统计时间：${new Date().toISOString().slice(0, 10)}`j2.alignment = { vertical: 'middle', horizontal: 'right' }j2.font = { size: 14 }worksheet.getRow(2).height = 40const header_title = ['tital1', 'tital2', 'tital3', 'tital4', 'tital5', 'tital6', 'tital7', 'tital8', 'tital9', 'tital10', 'tital11']worksheet.addRow(header_title)if (data && Array.isArray(data)) {data.forEach((item, index) => {worksheet.addRow([index + 1, item.code, item.name, item.type, item.unit, item.cangkuName, item.huoweiName, item.kucun, '', '', ''])})}const columnWidths = [7, 13, 19, 31, 12, 14, 19, 14, 11, 15, 23]columnWidths.forEach((width, index) => {worksheet.getColumn(index + 1).width = width})const alignment = {wrapText: true,vertical: 'middle',horizontal: 'center'}const borderStyle = {style: 'thin',color: { argb: 'ff000000' }}const border = {top: borderStyle,left: borderStyle,bottom: borderStyle,right: borderStyle}const data_rows = data?.length ? data.length + 3 : 13const data_cols = header_title.length || 11for (let row = 3; row <= data_rows; row++) {worksheet.getRow(row).height = 36for (let col = 1; col <= data_cols; col++) {const cell = worksheet.getCell(row, col)cell.font = { size: 12, bold: row === 3 }cell.alignment = alignmentcell.border = border // 设置边框}}const footer_rows = data_rows + 1worksheet.getRow(footer_rows).height = 30worksheet.mergeCells(`A${footer_rows}:B${footer_rows}`)const a14 = worksheet.getCell(`A${footer_rows}`)a14.value = '抽查人：'a14.font = { size: 14 }const e14 = worksheet.getCell(`E${footer_rows}`)e14.value = '核对人：'e14.font = { size: 14 }const k14 = worksheet.getCell(`K${footer_rows}`)k14.value = '准确率：'k14.font = { size: 14 }// 生成文件并下载const buffer = await workbook.xlsx.writeBuffer()saveAs(new Blob([buffer]), `导出数据_${new Date().toLocaleDateString()}.xlsx`)
}

后端nodeJS方法

使用node处理数据，再导出excel表格

安装

npm i exceljs

使用

const ExcelJS = require('exceljs')
const fs = require('fs')const exportExcel = async (data, filePath) => {const workbook = new ExcelJS.Workbook()const worksheet = workbook.addWorksheet('数据列表', {properties: { defaultRowHeight: 36, defaultColWidth: 20 },pageSetup: {horizontalCentered: true,verticalCentered: true,paperSize: 9,orientation: 'landscape',scale: 81,margins: {left: 0.25,right: 0.25,top: 0.75,bottom: 0.75,header: 0.3,footer: 0.3}}})// 按换行拆分let lines = data.split('\n').filter((line) => line.trim() !== '')const rows = lines.map((line) => line.split(' ').filter((item) => item.trim() !== ''))rows.forEach((row) => {worksheet.addRow(row)})// 设置所有单元格居中worksheet.eachRow((row) => {row.eachCell((cell) => {cell.alignment = { vertical: 'middle', horizontal: 'center' }})})const buffer = await workbook.xlsx.writeBuffer()// 保存文件fs.writeFileSync(filePath, buffer)console.log(`Excel文件已保存到 ${filePath}`)
}const str = `
