How to Convert Json Array to Single JSON object without using T object in C#?

Question

I am looking for a one-liner that transforms the Json array [{},{}] into object => [{}].

I have the following serialized JSON string,

 [
  {
    "Address": "Adresse"
  },
  {
    "AddressDetails": "Détails de l'adresse"
  },
  {
    "BackToLoginPage": "Retour à la page de connexion"
  }
]

Now I want to convert this into the following format without using one type or model object because the data is dynamic and it's going to contain 1000 number of fields so, I can not create a model type object with dynamic properties. So is there any idea to convert it into the one single JSON object/string?. It looks simple, but I couldn't convert it.

[
    "Address": "Adresse",      
    "AddressDetails": "Détails de l'adresse",      
    "BackToLoginPage": "Retour à la page de connexion"
]

Newtonsoft.Json.Linq can parse/process JSON without model (JObject/JArray). Here is one liner:

var mergedJson = new JObject(JArray.Parse(json).OfType<JObject>().SelectMany(o => o.Properties()).GroupBy(p => p.Name).Select(grp => grp.First())).ToString();
