I made it that way:
if I have:
var jsonArg1 = new Object();
jsonArg1.name = 'calc this';
jsonArg1.value = 3.1415;
var jsonArg2 = new Object();
jsonArg2.name = 'calc this again';
jsonArg2.value = 2.73;
var pluginArrayArg = new Array();
pluginArrayArg.push(jsonArg1);
pluginArrayArg.push(jsonArg2);
to convert pluginArrayArg (which is pure javascript array) into JSON array:
var jsonArray = JSON.parse(JSON.stringify(pluginArrayArg))

October 1, 2022 - The JSON.stringify() method converts a JavaScript object, array, or value to a JSON string.
Converting an array to a JSON object with custom key names
With and without Babel: https://jsfiddle.net/srxs4mcw/ The Babel summary: var arr = ["first", "second", "third", "fourth"]; var keys = ['one', 'two', 'three', 'four']; const newArr2 = arr.reduce((acc, val, i) => ({ ...acc, [keys[i]]: val }), {}); You reduce your array starting with an empty object. Each iteration spreads the accumulated object and adds the new array item to it. This one requires Babel to transpile your code. In my jsfiddle you'll also see a vanilla JS solution which is basically the same thing. More on reddit.com

July 1, 2022 Convert json to csv or XML ?
Csv is probably a simpler format to work with. I would start with writing a script that simply prints out with a loop the json file. Then modify the code in that loop to instead write it to a file comma separated (string manipulation). I'm sure if you googled or asked chatgpt you could get the basics of this pretty quick.
