Super-basic Minecraft Bedrock NBT Editor
What it is
Super-basic Minecraft Bedrock NBT Editor is a free Windows utility for changing selected world settings in a Minecraft Bedrock `level.dat` file. It edits the world name, game mode, difficulty, seed, spawn position, common gamerules, ability flags, and raw NBT values stored in that file. Its Re-enable Achievements action sets six listed experiment and creative-mode flags to 0, but it may not remove every achievement blocker: `commandsEnabled` and `experimentalgameplay` can remain set to 1. The editor does not modify the rest of the Bedrock save in the `db\` directory, which the project identifies as LevelDB data. When started, it automatically loads the first `level.dat` file it finds under the current folder. Changes made through the apply controls remain in memory until Save writes them to the file. Each save also creates a timestamped backup beside the world file. Users can launch the included Windows batch file or run the Python script. The repository lists an MIT license and no releases or packages.
For and against
For
- Edits common world settings and raw NBT values.
- Save creates a timestamped backup.
- Includes a Re-enable Achievements action.
- Free to use and lists an MIT license.
Against
- Does not edit the save's `db\` directory.
- Achievement blockers may remain after using the action.
- No releases or packages are listed.
The verdict
The editor focuses on a specific Bedrock world file and offers backups when saving. Its file scope is limited, and the achievement option may not clear all blockers.
Who it suits
This tool suits Windows users who want to edit selected settings or raw NBT values in a Bedrock world's `level.dat` file. It is not suited to editing the save's LevelDB data in `db\`.
