Convert all the integer value to string in JSON

Question

My JSON string is:

{name:\"MyNode\", width:200, height:100}

I want to change it to:

{name:\"MyNode\", width:\"200\", height         


        

Answer 1

That's a JavaScript object literal, not JSON. Anyway...

var obj = {name:"MyNode", width:200, height:100};

for (var k in obj)
{
    if (obj.hasOwnProperty(k))
    {
        obj[k] = String(obj[k]);
    }
}

// obj = {name:"MyNode", width: "200", height: "100"}

If you're actually working with JSON, not an object, JSON.parse() the string beforehand, and JSON.stringify() the object afterward.

Answer 2

If you must operate on the JSON string :

json = json.replace (/:(\d+)([,\}])/g, ':"$1"$2');

Answer 3

I use

const stringifyNumbers = obj => {                                                                                      
  const result = {};                                                                                                   
  Object.entries(obj).map(entry => {                                                                                   
    const type = typeof entry[1];                                                                                      
    if (Array.isArray(entry[1])) {                                                                                     
      result[entry[0]] = entry[1].map(entry => stringifyNumbers(entry));                                               
    } else if (type === 'object' && !!entry[1]) {                                                                      
      result[entry[0]] = stringifyNumbers(entry[1]);                                                                   
    } else if (entry[1] === null) {                                                                                    
      result[entry[0]] = null;                                                                                         
    } else if (type === 'number') {                                                                                    
      result[entry[0]] = String(entry[1]);                                                                             
    } else {                                                                                                           
      result[entry[0]] = entry[1];                                                                                     
    }                                                                                                                  
  });                                                                                                                  
  return result;                                                                                                       
}   

most ids should be strings in my opinion. If your api cannot provide ids as strings this snippet will convert them.
