Create a valid datapack zip with pack.mcmeta, the right pack format, and your functions or tags ready to drop in.
Set the pack details, add files or a folder, then download a zip ready for your world’s datapacks folder.
If you build with no files, a starter function and load tag are included automatically.
Create a valid Minecraft datapack zip online — pack.mcmeta, pack format for your game version, functions, and tags — then download an archive ready for your world’s datapacks folder.
A datapack needs the right folder layout and a pack.mcmeta that matches your Minecraft version’s pack format. Missing either causes /datapack list to ignore your work. This packer builds the metadata, namespace paths, and zip for you.
Set a display name and namespace, choose the pack format for 1.20 or 1.21-era versions, add a quick function or upload files, preview the tree, and download the zip.
Add mcfunction files under your namespace, include load or tick tags when you want functions to run automatically, and keep the tree tidy before you ship to production. Empty packs still get a valid starter layout so you are never stuck with a broken archive.
Use the packer for mini-game logic, custom crafting support packs, and event scripts you want staff to drop in without hand-building folders on the host.
Place the datapack folder or unzipped contents into world/datapacks (or the world name you use), then run /reload or restart. Confirm with /datapack list and fix any errors shown in the console.
Version upgrades sometimes change pack format numbers — rebuild the zip with the new format when you move between major Minecraft releases.
