Datapack Content Builders
Build JSON for custom enchantments, jukebox songs, paintings, armor trims, mob variants, dialogs, and banner patterns.
These builders target Minecraft’s 1.21+ data-driven JSON registries. Some schemas (mob variants, dialogs) are newer and still evolving — double check against the current version’s vanilla data before shipping.
