What Project Lodestone is

Project Lodestone is a free, open-source toolset for editing and converting Minecraft worlds across Java, Bedrock, console, and other editions. It has desktop and web interfaces, with the web platform listed for use. Its documentation covers Java, Bedrock, Raspberry Pi, Xbox 360, PlayStation 3 and 4, PlayStation Vita, Wii U, 3DS, Switch, and Classic Javascript Remake. The project is still in development, and its roadmap sets out a broad set of planned tools: editing player, region, chunk, and level data; converting worlds across editions and versions; and adjusting depth or recalculating lighting during conversion. Planned editors include tools for biomes, entities, block entities, hex data, LevelDB, datapacks, map items, and file formats. Those formats include NBT, S-NBT, MCR/MCA, GRF, MCS, ARC, LOC, PCK, COL, FUI, CDB, and VDB. The libLodestone library provides file reading and writing, as well as world and format conversion for many Minecraft editions and versions. The app’s roadmap describes loading and exporting worlds, levels, regions, and chunks as planned user-facing work. Some converter versions are not yet available in the app, and many documented versions remain expected support rather than completed work. Project Lodestone is not an official Microsoft, Minecraft, or Mojang Studios product.
