A Minecraft mod that helps datapack developers quickly browse and export registry data.

On top of that, DataDumper prevents game crashes caused by invalid datapacks, so you can debug with peace of mind.

- List all registries in the game
- Filter registry contents by tag or regex
- Export registry entries as JSON files
- Export datapack entries that failed to parse, making it easy to track down errors
