json转excel

主要使用 sheetjs 库

vim convertJsonToExcel.js 封装转换方法

import fs from 'fs';
import XLSX from 'xlsx';/*** 扁平化嵌套json对象* @param {Object} jsonObj* @param {String} prefix* @returns*/
export function flattenKeys(jsonObj, prefix = '') {const result = {};for (const key in jsonObj) {const value = jsonObj[key];const newKey = prefix ? `${prefix}/${key}` : key;if (typeof value === 'object' && value !== null) {Object.assign(result, flattenKeys(value, newKey));} else {result[newKey] = value;}}return result;
}/*** 转换 json 对象数据* @param {Object} data* @returns*/
export function adaptData(data) {const jsonDataFlat = flattenKeys(data)let result = []let count = {}//excel: key	module	source	contextObject.entries(jsonDataFlat).forEach(([key, value]) => {let keyArr = key.split('/')let item = {key: keyArr.join('.'),// module: keyArr.slice(0, -1).join('/'),module: 'data',source: value,context: '',}result.push(item)})return result
}
export const convertJsonToExcel = async (jsonFilePath, excelFilePath) => {const jsonData = JSON.parse(await fs.promises.readFile(jsonFilePath, 'utf8'));/*** @example data* ```[{ Name: "Bill Clinton", Index: 42 },{ Name: "GeorgeW Bush", Index: 43 },]* ```*/const dataArray = adaptData(jsonData)const headerArr = [['i18n key json']]const worksheet = XLSX.utils.json_to_sheet(dataArray, {origin: 'A2'});XLSX.utils.sheet_add_aoa(worksheet, headerArr, {origin: 'A1'})// 合并单元格worksheet['!merges'] = [// s:start, e: end, c: column, r: row{s: {c: 0, r: 0},e: {c: 4, r: 0}}]const workbook = XLSX.utils.book_new();XLSX.utils.book_append_sheet(workbook, worksheet, 'Sheet1');XLSX.writeFile(workbook, excelFilePath);
}

调用转换方法
vim convert.js

import fs from 'fs';
import {convertJsonToExcel} from './convertJsonToExcel.js'
import jsonData from './data.js'// 实际使用不需要此步骤，已经把js对象转换成json文件
fs.writeFileSync('data.json', JSON.stringify(jsonData), 'utf-8')
convertJsonToExcel('data.json', 'output.xlsx')

json对象示例

{"common": {name: '名称'}
}
