MongoDB 数据转为CSV文件

//格式化时间
Date.prototype.format = function(fmt) { 
     var o = { 
        "M+" : this.getMonth()+1,                 //月份 
        "d+" : this.getDate(),                    //日 
        "h+" : this.getHours(),                   //小时 
        "m+" : this.getMinutes(),                 //分 
        "s+" : this.getSeconds(),                 //秒

     for(var k in o) {

             fmt = fmt.replace(RegExp.$1, (RegExp.$1.length==1) ? (o[k]) : (("00"+ o[k]).substr((""+ o[k]).length)));

    return fmt;

var t={

db.getCollection('collection_person').find({"companyId":"1234567890"}).skip(0).limit(2000).forEach(

   function(doc){
       var str = "";
       str += doc._id + ",";
       str += doc.personId + ",";

       str += doc.employeeId + ",";

       if(doc.status == 1 || doc.status == 7) {
           str += doc.balance/100 + ",";
       } else {
           str += "0,";
       }
       str += doc.recoveryAmount/100 + ",";
       
       str += doc.createTime.format("yyyy-MM-dd hh:mm:ss") + ",";
       str += doc.updateTime.format("yyyy-MM-dd") + ",";       
       var ss = "";
       for(var i=0;i<doc.consumeTypeList.length;i++) {
          if(ss.length>0) { 
            ss+="、";
          }
          ss += t[doc.consumTypeList[i] + ""];
       }
       str += ss;
       
       print(str)
   }
)

 从控制太copy出打印数据，放到空白文件中，后缀名改为xxx.csv。

一切OK！！！！
