Preserving quotation marks when utilizing JSON parsing

Question

Preserving quotation marks when utilizing JSON parsing

Whenever I try to search for an answer to this question, I am unable to find any relevant results. So please excuse me if this has been asked before in a different way.

I want to preserve all quotation marks in my JSON when converting from a string.

In my user interface, there is a text field (string) where users will input some JSON that looks like this:

{ "example": "example" }

I want all the quotation marks to stay in my JSON object. But, when I use JSON.parse() on the string above, it strips away the quotes and gives me this:

{ example: "example" }

Is there a way to prevent the removal of the quotation marks?

Answer №1

JavaScript objects, which are the result of JSON.parse(), differ from actual JSON format. When working with objects, you do not necessarily need to use quotes unless the property names contain special characters. This allows for accessing properties both with and without quotes in your code.

const myObj = { example: "example" };

Both of these methods are valid:

console.log(myObject.example)
console.log(myObject["example"])

If you were to apply JSON.stringify() to this object again, it would display with proper quotes within the JSON string like so:

{ "example": "example" }

When using JSON.parse(), the output will be a javascript object as expected.

To match your backend's requirement of a JSON string, you must utilize JSON.stringify() on your javascript object.

let userInput = '{ "example": "example" }';
let userObject = JSON.parse(userInput);
let resultJson = JSON.stringify(userObject);

console.log(userInput);
console.log(userObject);
console.log(resultJson);

This code snippet yields:

{ "example": "example" }
{ example: 'example' }
{"example":"example"}
