CopyComponent
by Bishops_exe
CopyComponent lets a player copy the component or NBT data of an item held in the inventory, so the stored values can be read or reused.
What it does
Hovering over an item and triggering the copy action stores its component data as text. The data is written to a plain text file that can be opened in any editor, so the values can be read directly or pasted into another tool. Opening the inventory-style screen shows the available item data before anything is copied, which keeps the process visible to the player.
The mod runs on the client alone, so a server does not need it and players can join a server without installing it. It depends on Fabric API, which must be present on the client as well. Builds are published for Fabric, Forge, NeoForge and Quilt for 1.21.11 only, with version 1.0.0 dated 2026-02-15, and the code is released under the MIT License as open source.
Key features
Component and NBT copying
Copies the component or NBT data of an item into a text file, so the stored values can be read outside the game.
Inventory-style screen
Opens a screen resembling the inventory to browse items and choose which one to copy from.
Hover-based selection
Hovering over an item marks it as the target of the copy action, so the right stack is picked without extra steps.
Readable text output
The copied data is saved as a plain text file that can be opened and read with any text editor.

Use cases
Inspecting item data
A player wanting to see the exact component values on an item can copy them to a file and read the contents without using commands.
Reusing item data
Copied component text can be taken from the file and used as a reference when rebuilding or comparing an item in a world.
Who it’s for: Players and modpack builders who work with item component or NBT data and want to read it from a text file rather than through commands. The mod suits single-player and multiplayer clients alike, since only the client needs it.
