DataDumper

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

About

Ever found yourself constantly needing to check what's inside a registry while developing datapacks? Or wanting to filter for specific blocks and items?

DataDumper lets you browse registries directly in-game via commands, with support for tag and regex filtering. You can also export registry entries as JSON files for easy debugging.

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

Features

• 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
• Prevent crashes when creating a world with invalid datapacks
• Click chat messages to copy all entries at once

Commands

Exported files are saved in the .datadumper/ folder under the server's working directory.
