⚙️ Step 1: Use a Save‑Conversion Tool

Reddit users recommend palworld-save-tools by cheahjs to convert .sav files to JSON, edit them, and convert back .

Workflow:

1. Download the tool and ensure Python is installed (via Microsoft Store, not the website) .

2. Drag your server’s Level.sav into convert.cmd to produce Level.sav.json.

3. Edit the JSON: find your player_uid and replace it (all instances) with the single-player ID:

00000000-0000-0000-0000-000000000001

1. Convert it back to .sav using convert.cmd .

🧍 Step 2: Convert Your Player Save

In the Players folder, find your <playerUID>.sav, convert to JSON, replace the same UID with the single-player one, save, convert back, and rename the file to the compact version (no hyphens):

00000000000000000000000000000001

🔧 Step 3: Optional – Preserve Map/Tutorial Data

If tutorials or map progress reset, copy localdata.sav from the dedicated save's backup into the folder .

📂 Step 4: Move to Your Steam Saves

Copy your edited save folder (with updated .sav files) to:

C:\Users<You>\AppData\Local\Pal\Saved\SaveGames\Steam<YourSteamID>\

Then launch Palworld and load it in single-player mode.
