MCA JSON vs MCBE Inventory Editor

MCA JSON is a command-line toolkit and TypeScript library for handling Minecraft Java Edition region and data files. Its commands convert MCA and NBT data to JSON and back, list chunks, find signs, remove chunks, and inspect player locations. The library supplies typed methods for parsing and changing MCA, NBT, and SNBT data. The maker reports region structure and NBT reading across versions, with files tried from Minecraft 1.2.1 through 1.21. It reads zlib, gzip, LZ4, and uncompressed chunks; changes are saved with zlib. Installation is documented through npm, with Deno, Bun, pnpm, and other package managers also usable. The library can be bundled for browser use, is distributed only as ES modules, and requires Node.js 20 or newer. It supports Java Edition, not Bedrock. Separate .mcc chunks over 1 MiB and chunks using custom compression cannot be read, though they can be listed and removed. A largely untouched region produced about 1 gigabyte of JSON in an example; compact and condensed output options are documented. The software is free.

MCBE Inventory Editor is a free local web editor for selected Minecraft Bedrock player data. It can edit hotbar, backpack, armor, offhand, ender chest, effects, abilities, and player values such as health, game mode, XP, hunger, saturation, position, and movement speeds. Inventory actions include moving, copying, and bulk operations. It supports versioned local-to-multiplayer player migration and full .mcbe-player.zip imports and exports. The editor runs locally or in Docker, with a browser interface intended for use on the same network from a laptop, tablet, or phone. Editing worlds works offline; internet access is used for user-triggered item database and vanilla icon updates. Writes create a backup, and the editor includes restore and revision checks, write gates, and world locks. Minecraft or the Bedrock server must be stopped before editing a world, and the project recommends keeping an independent complete copy until verification. This is not a public hosting service or unrestricted raw NBT editor; add-ons, opaque NBT, and unusual LevelDB structures may fall outside its design.
