Convert my playerpref back to obj

So after trail and lots of Errors i figured out how do it with out having make separate database.

 using System.Collections;
 using System.Collections.Generic;
 using UnityEngine;
 
 public class ItemDB : MonoBehaviour {
 
     public bool save;
     public bool load;
 
     public GameObject[] ItemPrefabs;
     public GameObject[] TerrianDB;
     public GameObject[] ObjsDB;
     public Vector3[] ObjPos;
     public string[] saved;
     public string[] savedname;
     public Vector3[] savedvec;
     public GameObject[] spawnobj;
     public int savedlength;
 
     // Use this for initialization
     void Start() {
 
     }
 
     // Update is called once per frame
     void Update()
     {
         TerrianDB = GameObject.FindGameObjectsWithTag("TerrianObj");
         ObjsDB = GameObject.FindGameObjectsWithTag("Obj");
         ObjPos = new Vector3[ObjsDB.Length];
 
 
         for (int i = 0; i < ObjsDB.Length; i++)
         {
             ObjPos[i] = ObjsDB[i].transform.position;
         }
         if (load)
         {
             LoadDB();
         }
         if (save)
         {
             SaveDB();
         }
     }
 
     void LoadDB()
     {
         savedlength = PlayerPrefs.GetInt("Num");
         saved = new string[savedlength];
         savedname = new string[savedlength];
         savedvec = new Vector3[savedlength];
         spawnobj = new GameObject[savedlength];
         for (int i = 0; i < savedlength; i++)
         {
             saved[i] = PlayerPrefs.GetString("Data" + i.ToString());
             savedname[i] = PlayerPrefs.GetString("Data1" + i.ToString());
             savedvec[i].x = PlayerPrefs.GetFloat("Datax" + i.ToString());
             savedvec[i].y = PlayerPrefs.GetFloat("Datay" + i.ToString());
             savedvec[i].z = PlayerPrefs.GetFloat("Dataz" + i.ToString());
         }
         for(int i = 0; i < ItemPrefabs.Length; i++)
         {
             for (int x = 0; x < savedname.Length; x++)
             {
                 if (ItemPrefabs[i].name == savedname[x].Replace("(" + x.ToString() + ")" ,"").Trim())
                 {
                     spawnobj[x] = ItemPrefabs[i];
                 }
             }
         }
         Spawn();
         load = false;
     }
 
     void Spawn()
     {
 
     }
 
     void SaveDB()
     {
         PlayerPrefs.SetInt("Num", ObjsDB.Length);
 
         for (int i = 0; i < ObjsDB.Length; i++)
         {         
             PlayerPrefs.SetString("Data" + i.ToString(), ObjsDB[i].name + ":" + ObjPos[i].ToString());
             PlayerPrefs.SetString("Data1" + i.ToString(), ObjsDB[i].name);
             PlayerPrefs.SetFloat("Datax" + i.ToString(), ObjPos[i].x);
             PlayerPrefs.SetFloat("Datay" + i.ToString(), ObjPos[i].y);
             PlayerPrefs.SetFloat("Dataz" + i.ToString(), ObjPos[i].z);
         }
         save = false;
     }
