When transferring a save between Singleplayer and Multiplayer in Project Zomboid, your character\u2019s inventory, stats, and position won\u2019t transfer unless you convert the players.db<\/code> file. This is because the formats used for storing player data differ between game modes.<\/p>\n\n\n\n

Convert Singleplayer Save to Multiplayer<\/h2>\n\n\n\n

Upload the World<\/h3>\n\n\n\n
\n

Follow our upload guide<\/a> to transfer your singleplayer world to the server.<\/p>\n<\/blockquote>\n\n\n\n

\n\n\n\n

Set Up Your Workspace<\/h3>\n\n\n\n

On your computer:<\/p>\n\n\n\n

1. Create a folder at any location you’d like on your computer (e.g., ZomboidConversion<\/code>) to keep track of files.<\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n

2. Inside your FTP program, go to:
\/Zomboid\/Saves\/Multiplayer\/YOUR_WORLD_NAME<\/code><\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n

3. Download the uploaded world\u2019s players.db<\/code> file.<\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n

4. Place it in your workspace folder and rename it to OldPlayers.db<\/code>.<\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n
\"\"<\/figure>\n\n\n\n
\n\n\n\n

Confirm Save Format<\/h3>\n\n\n\n

1. Download and install DB Browser for SQLite<\/a><\/strong><\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n

2. Open OldPlayers.db<\/code> in DB Browser from File > Open Database<\/code>.<\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n
\"\"<\/figure>\n\n\n\n

3. Click Browse Data<\/strong>, then select the localPlayers<\/code> table. If there is player data here, this confirms it\u2019s a singleplayer-format players.db<\/code><\/strong><\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n
\n\n\n\n

Delete the Server\u2019s players.db<\/code><\/h3>\n\n\n\n

1. In yourFiles<\/code> panel, delete the existing players.db<\/code> file to avoid format conflict.<\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n

\n\n\n\n

Generate a Multiplayer-Formatted DB<\/h3>\n\n\n\n

1. Start the server, this will regenerate a multiplayer compatible players.db<\/code> file.<\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n

2. Join the server and create a temporary character (any settings are fine as this will be overwritten later<\/em>).<\/p>\n\n\n\n

3. Leave and stop the server again.<\/p>\n\n\n\n

4. In your server\u2019s world folder, download the newly generated players.db<\/code>. Place it in your workspace and rename it to NewPlayers.db<\/code><\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n
\"\"<\/figure>\n\n\n\n

Copy Over Character Data<\/h3>\n\n\n\n

1. Open DB Browser<\/strong>, Open Database<\/strong>.<\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n

2. Locate your workspace folder<\/strong>, then open NewPlayers.db<\/code>.<\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n

3. Click Browse Data<\/strong>, then select the networkPlayers<\/strong> table. If there’s any player data in the table, you can confirm that newPlayers.db<\/code> is using the Multiplayer format<\/strong>.<\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n
\"\"<\/figure>\n\n\n\n

4. Now open OldPlayers.db<\/code> in DB Browser. Click Browse Data<\/strong>, then select the localPlayers<\/strong> table.<\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n
\"\"<\/figure>\n\n\n\n

5. In localPlayers<\/code>, locate your player\u2019s row:<\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n

Keep a reference of the x<\/code>, y<\/code>, and z<\/code> values<\/strong>, these represent your position in the world
\ud83d\udccc Copy and paste them into any note-taking app for later use<\/em><\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n
\"\"<\/figure>\n\n\n\n

Right-click the data<\/code> field<\/strong> (contains player info like traits, inventory, health)<\/p>\n\n\n\n

Click Copy as SQL<\/strong><\/p>\n\n\n\n

2. Click the Execute SQL<\/strong> tab at the top. <\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n

You’ll now be inserting the data you copied from oldPlayers.db<\/code> (your Singleplayer save) into the networkPlayers<\/code> table of the Multiplayer save.<\/p>\n\n\n\n

Use the following commands one at a time, replacing the placeholder values with your actual values.<\/p>\n\n\n\n

Step-by-Step SQL Commands<\/h4>\n\n\n\n
\n

Replace REPLACE_WITH_TABLE<\/code> with networkPlayers<\/code>, since you’re converting to Multiplayer.<\/p>\n<\/blockquote>\n\n\n\n

1. Update player data field (copied from Singleplayer):<\/p>\n\n\n\n

UPDATE \"main\".\"networkPlayers\"\nSET data = X'PASTE_YOUR_SQL_STRING_HERE'\nWHERE id = 1;<\/code><\/pre>\n\n\n\n
Paste only the inside of the VALUES()<\/code> from your copied SQL (do not<\/strong> include the INSERT INTO<\/code> part).
For example, if your copied SQL is:<\/p>\n\n\n\n
INSERT INTO \"main\".\"localPlayers\" (\"data\") VALUES (X'010100000000000000004628dbf6...');<\/code><\/pre>\n\n\n\n
Paste everything between<\/strong> VALUES(<\/code> and );<\/code> into 'PASTE_YOUR_SQL_STRING_HERE'<\/code>.<\/p>\n\n\n\n
2. Update X coordinate:<\/p>\n\n\n\n
UPDATE \"main\".\"networkPlayers\"
SET x = YOUR_X_VALUE
WHERE id = 1;<\/code><\/pre>\n\n\n\n
3. Update Y coordinate:<\/p>\n\n\n\n
UPDATE \"main\".\"networkPlayers\"
SET y = YOUR_Y_VALUE
WHERE id = 1;<\/code><\/pre>\n\n\n\n
4. Update Z coordinate:<\/p>\n\n\n\n
UPDATE \"main\".\"networkPlayers\"
SET z = YOUR_Z_VALUE
WHERE id = 1;<\/code><\/pre>\n\n\n\n
Click the Execute all\/selected SQL<\/strong> button (\u25b6\ufe0f) in the top-left of DB Browser.<\/p>\n\n\n\n
\"\"<\/figure>\n\n\n\n
Once you’ve run all four commands, go to Browse Data > networkPlayers<\/strong> to confirm the changes were applied.<\/p>\n\n\n\n
\"\"<\/figure>\n\n\n\n
