What it is

Super-basic Minecraft Bedrock NBT Editor is a free Windows utility for changing selected data in a Bedrock world’s level.dat file. It edits the world name, game mode, difficulty, seed, spawn position, common gamerules, ability flags, and raw NBT values in that file. The Re-enable Achievements action sets six listed experiment and creative-mode flags to zero, but commandsEnabled and experimentalgameplay may remain set to one and still block achievements. The editor does not modify the save’s db\ directory, identified as LevelDB data, and offers no region, terrain, entity, or batch editing. On launch, it automatically loads the first level.dat found under the current folder. Apply controls keep changes in memory until Save writes them to level.dat; each save creates a timestamped backup beside the world file. Start it with run_bedrock_nbt_editor.bat or run the Python script using python.\bedrock_nbt_editor.py. The repository lists an MIT license and no releases or packages. The Free plan costs nothing.

Strong points and limits

Strong points

  • Edits common level.dat world settings
  • Supports raw NBT values
  • Creates timestamped backups on save
  • Includes an achievement re-enable action
  • MIT-licensed project

Limits

  • Does not edit the db\ LevelDB directory
  • Achievement blockers may remain
  • No region, terrain, or entity editing
  • No batch operations

Who it suits

It suits Windows users who need to adjust selected Minecraft Bedrock world settings or raw NBT values in level.dat. It is not for editing the save’s LevelDB data or terrain and entity content.

Verdict

This editor handles focused level.dat changes and keeps timestamped backups, making it useful for targeted Bedrock world adjustments. Its scope stops at that file, and achievement re-enabling may require addressing remaining flags.
