What Project Lodestone is
Project Lodestone is a free, open-source toolset being developed to edit and convert Minecraft worlds across Java, Bedrock, console, and other editions. Its documentation covers editions including Java, Bedrock, Raspberry Pi, Xbox 360, PlayStation 3 and 4, PlayStation Vita, Wii U, 3DS, Switch, and Classic Javascript Remake. The project has desktop and web interfaces, while web is a listed platform. Its roadmap includes editing player, region, chunk, and level data, plus conversion between editions and versions with options such as depth fixing and lighting recalculation. Planned format tools name NBT, S-NBT, MCR/MCA, MCS, ARC, LOC, PCK, FUI, CDB, and VDB; supported world formats also include GRF and COL. Other planned tools include biome, entity, block entity, hex, LevelDB, datapack, and map item editors. libLodestone provides file reading, writing, and conversion for many Minecraft editions and versions. The app roadmap still treats user-facing loading and exporting as planned work, and some converter versions are not yet available. The project notes that many listed versions are expected support, not completed work.
