Run your decryption script in reverse using the exact same password and settings to re-encrypt the JSON text back into a binary file. Replace the old save file with this newly encrypted version.
To modify an encrypted save, you need to decrypt it into raw JSON text, edit the values, and re-encrypt it using the exact same algorithm and security key the game uses. Method 1: Community Web Translators (Easiest for Players)
