World Utils
by masa
World Utils is a Forge management mod with commands that edit Minecraft worlds, mainly the chunk NBT data that stores saved level information.
What it does
Several commands in World Utils change existing worlds directly. Most of them operate on chunk NBT data, the level storage that the game reads when it loads terrain, so a mistake can affect much of a save. The mod is released for Forge only, across the 1.10.2 – 1.12.2 range, with the 1.12.2 build as the latest file.
The server must run the mod to use the commands, while players may leave it out of their installs. The code is available under the GNU Lesser General Public License v3.0 only, so it is open source. The source code and issue tracker are public.
Key features
World editing commands
A set of commands edits saved worlds, fixing or altering data that the game does not expose through normal play.
Chunk NBT operations
Most commands read and write chunk NBT data, the per-chunk storage that holds terrain and block information.
Fix-oriented tools
The commands are aimed at repairing or adjusting worlds rather than changing gameplay during a session.

What the author says
World Utils adds several commands to manipulate or fix Minecraft worlds. Most of those operate at the Chunk NBT data level. I need to rewrite and clean up the documentation at some point...
