Javascript method for parsing specific fields from JSON, The JSON.parse() method parses a JSON string, constructing the If a reviver is specified, the value computed by parsing is transformed The JSON.parse() function is included in all major browsers and in the latest ECMAScript (JavaScript) standard. The numbers in the table below specifies the first browser version that fully supports the JSON.parse() function:

JSON.parse(j, (key, value) => key === 'fields' ? (fields = value) : value)
console.log( fields )
JavaScript JSON parse() Method, JSON.parse to convert JSON back into an object. specification, so some JavaScript-specific object properties are skipped by JSON.stringify . The JSON.parse () method parses a JSON string, constructing the JavaScript value or object described by the string.

JSON methods, toJSON, JSON's format is derived from JavaScript object syntax, but it is entirely JSON.parse() is a secure function to parse JSON strings and convert Later, you can then read the information with the JSON.parse() method and work with the data as needed. We’ll look at a JSON object that we assign to the variable obj , and then we’ll convert it using JSON.stringify() by passing obj to the function.
How To Work with JSON in JavaScript, parse() , and access it via “.” or “[]”. JavaScript. <script> var data = '{"name": "mkyong", Parsing JSON data is really easy in Javascript or Typescript.

How to access JSON object in JavaScript – Mkyong.com, My last post highlighted how you can quickly visualize JSON data with a function will return an array of keys that match on a certain value. The JSON.stringify() function converts a JavaScript object into a JSON string. Strings are lightweight and therefore very useful when transporting data from a client to a server. Let’s return our
Comments obj.records[0].fields
I think it's important to be clear here that since this is already a JavaScript Object (at least in the code you posted), there's no need for parsing, just simple property access as @CertainPerformance demonstrated. If that entire code was a String type, then you'd need to use JSON.parse(rawJsonString)
to make your object and then use property access. Might be best to clear up what you've got by editing your question to either: var obj = { ... }
or var jsonString = "{ ... }"
. You should also clarify if the array records
will have more than one value. Do you want an array of the 'fields' objects or will there always only be one? To answer Mark, yes records will be more then one, so data obj could be 10 records all structured the same way and I will need to loop through each for fields so obj.records[0].fields does give me the first field but obj.records[3].fields gives me the fourth listing I would like to have all fields as an array
