Is there a way to treat an object inside JSON as a String?

I'm working in Java, and I have some JSON that is kinda like this: 

{
    "objectList" : [{...}, {...}, ...], 
    "metadata" : {...}    
}

What I want to do is get the list and objects as JSON strings. So basically, I want to deserialize this JSON into an object like this: 

{
    "objectList" : "[{...}, {...}, ...]", 
    "metadata" : "{...}"    
}

So I can do further processing on those strings.

What's the best way to do this?

I'm hesitant to try to use String parsing to extract the data I need since the values inside those objects may affect how it's being parsed.

If I were you, I'd use some JSON-parsing library (such as Gson) to turn your JSON into a JsonObject. You can then simply get the value of objectList as a String using JsonObject#getAsString:

String json = "{\n" +
              "    \"objectList\" : \"[{...}, {...}, ...]\", \n" +
              "    \"metadata\" : \"{...}\"    \n" +
              "}";

JsonObject jsonObject = new Gson().fromJson(json, JsonObject.class);

System.out.println(jsonObject.get("objectList").getAsString());

Output:

[{...}, {...}, ...]
