Simple World Importer
by longnap
Simple World Importer adds a Singleplayer screen button for uploading a world .zip file so it can be added to the game in seconds.
What it does
A button on the Singleplayer screen accepts a world archive in .zip form and places the world into the saves list, so a player does not need to unpack files by hand. Importing takes only a few seconds once the archive is chosen. The world must match the game version it was saved in, or it may cause errors. The mod requires Fabric API and works with Fabric for 1.21.1. Both client and server need it, and the license is All rights reserved, so the code is not open source.
