How to convert Json file to Dictionary using C#-Unity

I'm trying to take a Json data set in Unity-C# and turn it into a Dictionary

{
1:
    {
        "uni_number": 001,
        "level" : 3,
        "Hp" : 15
    },
    2:
    {
        "uni_number": 000,
        "level" : 0,
        "Hp" : 0
    }
}

(I can have the intigers strings if needed) I also need to turn the dictionary file back into a json file when I want to save the game.

I've checked a couple of different StackOverflow questions and I can't seem to figure it out. I've tried using JsonUtility to parse it into a Dictionary.

Here's the json file I want to turn into a dictionary

string json = @"1:{""uni_number"": 001,""level"" : 3,""Hp"" : 15},2:{""uni_number"": 000,""level"" : 0,""Hp"" : 0}";

This is one of the things that I tried if I can get it to work than I should be able to finish it from there after I add another depth to it. 

string json = @"{""uni_number"": ""001"",""level"" : ""3"", ""Hp"": ""15""}";

Dictionary<string, string> loadedData = JsonUtility.FromJson<Dictionary<string, string>>(json);

This doesn't give me an error, but when I try to print it, it prints nothing. Here's how I print it.

foreach (KeyValuePair<string, string> kvp in loadedData)
        {
            print("Key = {0}, Value = {1}");
            print(kvp.Key);
            print(kvp.Value);
        }

I've also tried

string loadedData = JsonUtility.FromJson<string>(@"{""uni_number"": ""001"",""level"" : ""3"", ""Hp"": ""15""}");

print (loadedData)

and it doesn't print anything, so I think I'm using the JsonUtility function wrong, but I don't know how.

If I can't get it to work I could probably make my own function that turns json files into dictionarys, but it's probably going to be a big pain in the but.

I am using Newtonsoft.Json and it works : (notice that each value is a dictionary (key,value pairs) aswell)

     string json = @"{
                    1:
                    {
                        ""uni_number"": 001,
                        ""level"" : 3,
                        ""Hp"" : 15
                    },
                    2:
                    {
                        ""uni_number"": 000,
                        ""level"" : 0,
                        ""Hp"" : 0
                    }
                    }";

        var values = JsonConvert.DeserializeObject<Dictionary<string, Dictionary<string,string>>>(json);
        foreach (var uni in values)
        {
            //you can print values here or add to a list or ...
              string uni_number=  uni.Value["uni_number"];
              string level=  uni.Value["level"];
              string Hp=  uni.Value["Hp"];

        }
