Deserialize nested Json data

Hi. Please, could somebody help deserialize JSON from a file. I have no chance to do it alone. The result of the script is a empty dictionary.

P. S. I need to do this to make setting up of troops in unity editor faster

[System.Serializable]
public class TroopValues
{
    public int dps;
    public int health;
    public string name;
    public int price;
}

[System.Serializable]
public class LevelList
{
    public List<TroopValues> list = new List<TroopValues>();
}

[System.Serializable]
public class TroopsList
{
    public Dictionary<string, LevelList> dict = new Dictionary<string, LevelList>();

    public static TroopsList CreateFromJSON(string jsonString)
    {
        return JsonUtility.FromJson<TroopsList>(jsonString);
    }
}

// JSON (it is only a part of a json file)
{
  "MHN-1": [
    "{
\"dps\": 10,
\"health\": 150,
\"name\": \"MHN-1\",
\"price\": 10,

",
"{
"dps": 20,
"health": 200,
"name": "MHN-1",
"price": 20,
",
“{
"dps": 30,
"health": 250,
"name": "MHN-1",
"price": 30,
}”
]
}

JsonUtility uses Unity’s serialization system, which does not include a dictionary. Replace it with a list or array. Or use another plugin.
