About this Mod

A simple client-side mod that lets you view and copy the NBT data on an item. Simply hold the item in your main hand, and run the command /copyNBT and the mod will send the NBT data of the item in chat, along with a copy button.

For example, if you are holding a bow with the enchant flame, running the command would send the following in chat:

minecraft:bow{Damage:0,Enchantments:[{id:"minecraft:flame",lvl:1s}]}

Server lagging with Copy NBT – how to optimize performance?

Recommended RAM: 4 GB (per 8 players). Use /spark profiler to check if Copy NBT consumes the most tick time.
