Simple NBT Mod
Simple NBT Mod lets players copy and paste item NBT data through the clipboard, so a Fabric client can import and export item data on 1.21.1.
What it does
Chat commands handle most of the work: a copy command stores the NBT of the item in the player's hand on the clipboard, and a paste command builds a new item from the clipboard data. A show option displays the NBT in chat before anything is copied. Because the workflow depends on the clipboard, it works with text pasted from outside the game as well as text copied from it.
The mod is mainly meant for importing and exporting NBT, and much of the creative work is expected to happen outside Minecraft in a code editor. The author points to MCStacker for building item data, and the commands are described to use the format that MCStacker produces. Items placed in containers, including decorated pots, follow a required command format, and a short video on the project page shows the features in use.
Simple NBT Mod is a Fabric mod that runs on the client only, so servers and other players do not need it. It is released under the GNU General Public License v3.0 or later and is open source, with public source code and an issue tracker. Files are published for Fabric only, for 1.21.1, with version 1.0.0 as the latest file from 2024-10-02.
