If you use lift-json, you get exactly what you want :

scala> import net.liftweb.json._
scala> import net.liftweb.json.JsonDSL._

scala> val json = 
  ("person" ->
    ("name" -> "Joe") ~
    ("age" -> 35) ~
    ("spouse" -> 
      ("person" -> 
        ("name" -> "Marilyn") ~
        ("age" -> 33)
      )
    )
  )
scala> json transform {
         case JField("name", JString(s)) => JField("NAME", JString(s.toUpperCase))
       }
res8: net.liftweb.json.JsonAST.JValue = JObject(List(JField(person,JObject(List(
JField(NAME,JString(JOE)), JField(age,JInt(35)), JField(spouse,JObject(List(
JField(person,JObject(List(JField(NAME,JString(MARILYN)), JField(age,JInt(33)))))))))))))

The above codes are copied from the linked page.

If you don't use lift-json, you may take a look at kiama, as demonstrated in this answer.
