converting JS objects to a json file-CodePudding

Does anyone know the best way to convert an array of objects that look like this,

 {
    date: '22 Nov 2022 18:49',
    ticker: 'RYAN',
    security: 'RYAN SPECIALTY HOLDINGS Inc ',
    rep: 'RYAN PATRICK G',
    relationship: 'Chief Executive Officer, 10%',
    transaction: 'Purchase ',
    shares: '81,375',
    price: '37.5016'
  },

into a JSON file in java script. Thanks

I have tries Using stringify, but with no success. ERRR:

CodePudding user response：

Here is an example of converting an array of objects to json and save it in a file using Node.js.

Here is the example:

const person = {
 name: 'John Doe',
 age: 35,
 usesStackoverflow: true
};

The object inside an array

const persons = [
 person,
 person,
 person
];

Converting object or array to JSON:

const jsonContent = JSON.stringify(persons); // you can also use person object to convert object to json

Saving it to a file:

const fs = require("fs");
const path = require("path");

const pathToSave = path.resolve("persons.json");
fs.writeFileSync(pathToSave, persons);

CodePudding user response：

Use can use spread syntax to "explode" all the elements of the array into a single new empty object by using Object.assign

const arrayOfPeople = [{},{},{}]

// Merge an array of objects into a single object
const objectOfPeople = Object.assign({}, ...arrayOfPeople);

The error use received is cover pretty well in Chrome sendrequest error: TypeError: Converting circular structure to JSON
