Convert JS object to JSON string

Question

If I defined an object in JS with:

var j={\"name\":\"binchen\"};

How can I convert the object to JSON? The output string should be:

Answer 1

you can use native stringify function like this

const j={ "name": "binchen" }

/** convert json to string */
const jsonString = JSON.stringify(j)

console.log(jsonString) // {"name":"binchen"}

Answer 2

You can use JSON.stringify() method to convert JSON object to String.

var j={"name":"binchen"};
JSON.stringify(j)

For reverse process, you can use JSON.parse() method to convert JSON String to JSON Object.

Answer 3

I was having issues with stringify running out of memory and other solutions didnt seem to work (at least I couldn't get them to work) which is when I stumbled on this thread. Thanks to Rohit Kumar I just iterate through my very large JSON object to stop it from crashing

var j = MyObject;
var myObjectStringify = "{\"MyObject\":[";
var last = j.length
var count = 0;
for (x in j) {
    MyObjectStringify += JSON.stringify(j[x]);
    count++;
    if (count < last)
        MyObjectStringify += ",";
}
MyObjectStringify += "]}";

MyObjectStringify would give you your string representaion (just as mentioned other times in this thread) except if you have a large object, this should also work - just make sure you build it to fit your needs - I needed it to have a name than array
