MCPIedit is a level.dat world configuration file for MCPI and MCPE. It modifies the NBT data inside level.dat files by removing the headers, and with the pynbt module. Currently, it can modify

- World name

- Gamemode

- Seed (read only)

- Inventory

- Armour

It can also modify multiplayer worlds if the world is converted to singleplayer first by loading it in MCPI or MCPE
