install

nodejs v12 is required. run:

npm install -g minecraft-world-splicer

usage

minecraft-world-splicer \
  --source-world=path/to/source-world
  --source-x=0 --source-z=0 
  --source-width=1 --source-height=1
  --target-world=path/to/target-world
  --target-x=0 -target-z=0

option	description
--source-world	the world to copy chunks from
--source-x --source-z	chunk coordinates (not block coordinates) in the source world to copy from
--source-width --source-height	how many chunks to copy
--target-world	world to copy chunks into. its world generation and inventories will be kept. any chunks overlapping with the copied chunks will be overwritten
--target-x -target-z	chunk coordinates in the target world to copy to. the point corresponding to the source coordinates will be copied to this point.

please for miku's sake make a backup

this tool has been tested somewhat but it will overwrite chunks in the target world without prompting and it might corrupt your world.

thanks

to @rowanmanning for testing and moral support and the Prismarine project for already having done the hard bits
