A method to transform all JSON values into strings without needing to loop through each one

I need to convert all values in a JSON object into strings. These values could be numbers, booleans, undefined, or null.

{
    "obj1": [{
        "n1": "n",
        "n2": 1,
        "n3": true
    },
    {
        "n1": "n",
        "n2": 1,
        "n3": null
    }]
}

The desired outcome is for all values to be converted to string.

Example:

{
    "obj1": [{
        "n1": "n",
        "n2": "1",
        "n3": "true"
    },
    {
        "n1": "n",
        "n2": "1",
        "n3": "null"
    }]
}

We can achieve this by iterating through the JSON object, but I am wondering if there is a simpler method to accomplish this task.

Answer №1

To transform values into a string or keep them as is, you can utilize JSON.stringify along with a replacer function which verifies if the value is a number.

var object = { obj1: [{ n1: "n", n2: 1, n3: true }, { n1: "n", n2: 1, n3: null }] },
    json = JSON.stringify(object, (k, v) => v && typeof v === 'object' ? v : '' + v);

console.log(json);
console.log(JSON.parse(json));

To achieve this, you can utilize the Json.stringify() method.

For instance:

var data = { info1: [{ num1: "n", num2: 1, num3: true }, { num1: "n", num2: 1, num3: null }] };

To view the output, simply employ the Json.stringify() method:

console.log(JSON.stringify(data, (key, value) => value ? value.toString() : value));

const myObject = {
    "item1": [{
        "value1": "v",
        "value2": 1,
        "value3": true
    }, {
        "value1": "v",
        "value2": 1,
        "value3": null
    }]
};
const data = JSON.stringify(myObject)
const updatedObject = data.replace(/:([^"[{][0-9A-Za-z]*)([,\]\}]?)/g, ':\"$1\"$2')
console.log(updatedObject);
/*
{"item1":[{"value1":"v","value2":"1","value3":"true"},{"value1":"v","value2":"1","value3":"null"}]}
*/

// Let's format it for better readability
console.log(JSON.stringify(JSON.parse(updatedObject), null, 2));
/*
{
  "item1": [
    {
      "value1": "v",
      "value2": "1",
      "value3": "true"
    },
    {
      "value1": "v",

      "value3": "null"
    }
  ]
}
