This mod provides a command to view and modify any player's inventory, hotbar, ender chest, armor, and offhand slots (requires level 4 admin privileges).

When installed on the client, it provides in-game interface translations.

Supports en_us, zh_cn, zh_hk, and zh_tw languages.

Important:

Required on the server, optional on the client.
For the time being, it is not supported to view or modify the data of offline players (offline players refer to those who are not currently online, not to players who log in via offline mode).
Creative inventory problem.
