Help, how to make this unity save and load system work?

using UnityEngine;
using System.Collections.Generic;
using System.IO;

public class TestSaveSyst : MonoBehaviour
{
    public List<GameObject> ListOfGameObjects;
    public List<NormalObject> objectsToSave;
    public List<NormalObject> LoadedObjects;
    public string fileName = "savedObjects.json";

    public ListObjectToSave listObjectToSave;

    void Awake()
    {
        listObjectToSave = new ListObjectToSave();
    }

    void OnEnable()
    {
        objectsToSave = listObjectToSave.objectsToSave;
    }

    public void GOListToNOList() // Turns ListOfGameObjects to objectsToSave
    {
        foreach(GameObject go in ListOfGameObjects)
        {
            objectsToSave.Add(TurnGameObjectToNormalObject(go));
        }
    }

    public NormalObject TurnGameObjectToNormalObject(GameObject go)
    {
        NormalObject newNorm = new NormalObject();
        newNorm.name = go.name;
        newNorm.x = go.transform.position.x;
        newNorm.y = go.transform.position.y;
        return newNorm;
    }

    public void Save()
    {
        string json = JsonUtility.ToJson(objectsToSave);
        File.WriteAllText(Application.dataPath + "/" + fileName, json);
    }

    public void Load()
    {
        if (File.Exists(Application.dataPath + "/" + fileName))
        {
            string json = File.ReadAllText(Application.dataPath + "/" + fileName);
            LoadedObjects = JsonUtility.FromJson<List<NormalObject>>(json);
        }
        else
        {
            Debug.Log("File not found!");
        }
    }
}
