To serialize arrays in JSON, a "wrapper class" might look like this:

// from https://stackoverflow.com/questions/36239705/serialize-and-deserialize-json-and-json-array-in-unity  
public static class JsonHelper  
{  
    public static T[] FromJson<T>(string json)  
    {  
        Wrapper<T> wrapper = JsonUtility.FromJson<Wrapper<T>>(json);  
        return wrapper.Items;  
    }  
  
    public static string ToJson<T>(T[] array)  
    {  
        Wrapper<T> wrapper = new Wrapper<T>();  
        wrapper.Items = array;  
        return JsonUtility.ToJson(wrapper);  
    }  
  
    public static string ToJson<T>(T[] array, bool prettyPrint)  
    {  
        Wrapper<T> wrapper = new Wrapper<T>();  
        wrapper.Items = array;  
        return JsonUtility.ToJson(wrapper, prettyPrint);  
    }  
  
    [Serializable]  
    private class Wrapper<T>  
    {  
        public T[] Items;  
    }  
}

and then call something like
string mySaveData = JsonHelper.ToJson<array_type>(ARRAY);
