Read world seed, spawn point coordinates, and persistent spawn chunk boundaries directly from your local level.dat save file.
Data for Minecraft 26.3All processing is performed directly in your web browser. No save data is ever uploaded to any server.
Drag and drop a Minecraft level configuration file onto the drop zone or use the file browser button to load it. The application parses world identity, seed, spawn coordinates, and active game rules client-side without uploading any files. Inspect the interactive map preview to locate the spawn chunk boundary.
Ensure that the selected file is named level.dat and belongs to a supported Java or Bedrock world save. If loading fails, verify that the file is not locked by a currently running game instance. Use the goto fields to navigate across distant coordinates.
Loaded spawn chunk radius values from older releases are not included in official server data extraction and appear as a gap notice. Bedrock worlds store spawn coordinates with varying vertical offsets depending on sub-chunk generation state.
