大型json，将两个字段存储在数组中 [英] Large json, store two fields in an array

问题描述

我有一个大的json文件，需要将字段合并到一个数组中才能存储到firestore。

I have a large json file that needs to have to "fields" merged in to an array in order to store to firestore.

这里是一个屏幕截图，显示了什么我的意思是。我拥有的东西：

Here a screenshot to show what I mean. What i have:

我需要什么：

What I need:

您可以看到GRP1D和GRP2D合并到一个数组中。 json有15000个条目，因此手动操作是不可行的

As you can see GRP1D and GRP2D where merged in to an array. The json has 15000 entries so doing it manually is not an option

推荐答案

以下是使用扩展运算符的小代码段

Here is small code snippet using the spread operator

const your_data = require("./your_data/ file/path");
const prepare_func = (your_data)=>{
  let temp = {...your_data,"GRP1D":[your_data["GRP1D"],your_data["GRP2D"]]};
  return temp;
}
let new_data = prepare_func(your_data);
