The record

Purpose: Chunkweave edits structured Minecraft Java Edition data in a browser.

World and player data: It can edit level.dat, playerdata, and other compressed NBT containers.
Structures: For structure files, it can inspect structure blocks, entities, palettes, and metadata.
Region browsing: For Anvil regions, it shows populated chunks on a 32×32 map before opening their NBT.
Local processing: The editor parses and rebuilds files in a browser Web Worker; the maker says opened world files are not uploaded, stored, or received by Chunkweave.
Separate-copy export: Edits are rebuilt locally and downloaded as a separate file, leaving the original untouched.
Undo and redo: The workspace includes undo and redo controls before download.
