Unity Save Edit Instant
First, you need a class to hold your data. It must be Serializable so Unity can convert it to text (JSON) for saving.
[System.Serializable]
public class PlayerData
public string playerName;
public int level;
public float health;
public Vector3 position; // Note: Vector3 is supported by JsonUtility
You don’t need to be a programmer, but you need the right toolset. Here are the essential tools every Unity save editor should have: unity save edit
| Tool | Purpose |
|------|---------|
| Notepad++ or VS Code | View and edit plain text/JSON files. |
| HxD (or any hex editor) | Edit binary/encrypted files at the byte level. |
| 7-Zip | Some Unity games save data inside ZIP archives (renamed as .sav). |
| UnityPy or AssetStudio | Extract Unity assets to understand save structure. |
| Base64 Decoder (CyberChef) | Decode Base64-encoded save data. |
| Python (optional) | Write scripts to automate XOR decryption or re-checksum. |
| Save Editor Online (e.g., SaveEditOnline) | For popular games with community-made editors. | First, you need a class to hold your data
If you update your game and remove the currentHealth variable but the player tries to load an old save file, it might cause errors.
Solution: JSON is forgiving (it will just ignore missing fields), but for complex systems, include a version integer in your PlayerData class so you can handle legacy save files during loading. You don’t need to be a programmer, but
Hollow Knight uses a custom binary format with a magic header. You cannot simply edit the number of “Geo” (currency) with a hex editor without also updating the checksum. The community created a dedicated save editor for this purpose.
