How to Edit Level Data on a Minecraft Server

Edit your world's level.dat (spawn point, time, game rules and more) in the panel's NBT editor.

Updated 1 min read

level.dat stores a world's settings: its spawn point, time, weather, game rules, difficulty and more. The panel can open it in an NBT editor, so you don't need a tool on your computer.

Warning

A mistake in level.dat can stop the world loading. Create a backup in Backups before you edit it.

Edit it

  1. In Console, click Stop. The server rewrites level.dat when it saves, which would undo your changes.
  2. Go to Files and open your world folder (usually world).
  3. Click level.dat. It opens in the NBT editor, with everything under a Data tag.
  4. Use Search NBT tags or Search tags and values to find what you want.
  5. Change the value and save.
  6. Start the server from Console.

Useful tags

Tag What it is
SpawnX, SpawnY, SpawnZ The world spawn point
DayTime, Time Time of day and total world age, in ticks
raining, thundering Current weather
GameRules Every game rule, e.g. keepInventory
Difficulty, hardcore Difficulty and hardcore mode
LevelName The name shown for the world

Most of these are easier to change with commands while the server runs (setworldspawn, time set, gamerule). Use the NBT editor for what commands can't reach, or when the server won't start.
