1 script, but apply to be applied to many others

I have this basic script that will convert a basic File and turn it into a .txt file and back again. My problem is that in my Save and Load methods, I want to be able to put any file reference into it without having to make several copies of that same script.

using UnityEngine;
using System.IO;

[System.Serializable]
public class SaveLoadSystem
{

public string FileLocation;
public string Filename;

public void GetPath()
{
    FileLocation = Path.Combine(Application.dataPath + "/" + FileLocation, Filename + ".txt");
}

public void Save(MonoBehaviour Data)
{
    string DataInfo = JsonUtility.ToJson(Data);
    File.WriteAllText(FileLocation, DataInfo);
}

public void Load(ScriptableObject Data)
{
    string DataInfo = File.ReadAllText(FileLocation);
    JsonUtility.FromJsonOverwrite(DataInfo, Data);
}
}

I want to be able to put this into another script and say, save Obj1 file, but not have to put (Obj1 Data) in the save and load methods. I want to make them universal~ So I can say Save Obj2 file from one script and then maybe say save Obj3 file from another one, but not have a separated script for each Obj I want to save.

You can make an extension of monobehaviour

 public static class SaveLoadSystem
{
public static string FileLocation; //you'll have to set this inside the save & load
public static void Save(this MonoBehaviour Data) {
     string DataInfo = JsonUtility.ToJson(Data);
     File.WriteAllText(FileLocation, DataInfo);
}

 public static void Load(this ScriptableObject Data)
 {
     string DataInfo = File.ReadAllText(FileLocation);
     JsonUtility.FromJsonOverwrite(DataInfo, Data);
 }
}

then you can just do on any MonoBehaviour or ScriptableObject you can do .Save(); or .Load()

You will have to set FileLocation inside the save & load
you could probably do the path combine with the Data.name
