💡 How to Use

Locate `level.dat`: Find the `level.dat` file inside your Minecraft Java Edition world's save folder. (On Windows, usually in `%appdata%\.minecraft\saves\YourWorldName\`). This tool does not support Bedrock Edition `level.dat` files.
Upload File: Click the "Open File..." button and select your `level.dat` file, OR drag and drop the file directly onto this page.
View Results: If the file is valid, the tool will display:
- Your World Name, Seed, and exact Spawn coordinates (X, Y, Z).
- A map centered on your spawn point showing the Spawn Chunks colored by activity level.
Understand the Map:
- Green Chunks: Fully active spawn chunks (entities process, blocks tick, etc.).
- Yellow Chunks: Partially active (entities process, blocks don't tick randomly - sometimes called entity-ticking chunks).
- Grey Chunks: Lazy chunks (minimal processing, load when player nearby).
(See the Minecraft Wiki for more details.)
Navigate Map: Use drag/zoom or the controls below the map to explore the area around your spawn chunks.
