Change key name in nested JSON structure

Question

I have a JSON data structure as shown below:

{
    \"name\": \"World\",
    \"children\": [
      { \"name\": \"US\",
          \"children\": [
           {          


        

Answer 1

I don't know why you have a semicolon at the end of your JSON markup (assuming that's what you've represented in the question), but if that's removed, then you can use a reviver function to make modifications while parsing the data.

var parsed = JSON.parse(myJSONData, function(k, v) {
    if (k === "name") 
        this.key = v;
    else if (k === "children")
        this.value = v;
    else
        return v;
});
