I get a JSON string using Watson,

How do I change a node in this json string.

I've tried to serialize this string of json strings and when I deserialize it I lose data in the json,

So I want to know how I can change the json string that I get from Watson, is there a way to do that?

Hello Chen Yabin!

Could you provide a simplified example?  Or is it as simple as you receive something like:

{ "name": "Craig" }

And you want to change it to something like:

{ "firstName": "Craig" }

Also, are you using the built-in JSON deserialization capabilities, or are you using something like ardoJSON?
