json文件转换xlsx文件(Nodejs)
2016-12-14
前言
实现xls与json格式互转,推荐结合阅读:
excel文件转换json文件(nodejs|python)
正文
使用插件:json2xls
官方页有简单的示例,在此基础上扩展为转换指定的json文件。
GitHub:
https://github.com/pury/SPTools/tree/master/json2xls
var fs = require("fs");
var json2xls = require('json2xls');
var args = process.argv.splice(2);
if (args && args.length)
{
var file = args[0];
fs.readFile(file, "utf8", (err, data) => {
if (err)
{
throw err;
}
try
{
var jsonData = JSON.parse(data);
var xls = json2xls(jsonData);
var fileName = file.split(".")[0];
fs.writeFileSync(fileName + ".xlsx", xls, "binary");
console.log("Success!");
}
catch (e)
{
throw e;
}
});
}
else
{
console.log("Please input a file name");
}
使用方法:
$ npm install json2xls $ node go.js 文件名
注意:
excel文件为二维表单,json对象应为符合插件要求的格式,可视为元素为对象的一维数组,如果不符合要求,需要自行转换。
