Data Command Plus
Java mod listed for Minecraft 1.21. Downloads from the MC Java Mods app on Android.
I don't know my version or loader
Open the Minecraft launcher and look at the profile you play on — it names both, like fabric-loader-1.21.4. The version also shows in the bottom-right corner of the game's main menu.
No loader in the profile name? Then it's plain Minecraft, and these mods won't run — you need Fabric or NeoForge installed first.

Squished tree: of /data command
- … get (block <targetPos>|entity <target>|storage <target>|storageplayer <player>) [<path>] [<scale>]
- … merge (block <targetPos>|entity <target>|storage <target>|storageplayer <player>) <nbt>
- … modify (block <targetPos>|entity <target>|storage <target>|storageplayer <player>) <targetPath> (append|insert <index>|merge|prepend|set| operation)
- … from (block <sourcePos>|entity <source>|storage <source>|storageplayer <player>) [<sourcePath>]
- … concat (block <sourcePos>|entity <source>|storage <source>|storageplayer <player>) [<sourcePath>]
- … string (block <sourcePos>|entity <source>|storage <source>|storageplayer <player>) [<sourcePath>] [<start>] [<end>]
- … <(operation one of: =, +=, -=, *=, /=, %=, ^=, <, >)> <double value>
- … value <value>
- … remove (block <targetPos>|entity <target>|storage <target>|storageplayer <player>) <path>
Squished tree: of /Loot command
/loot <TARGET> <SOURCE>where
<TARGET> is:
- give | insert | spawn | replace <targetPos>
- insert entity <to entity> inventory <from entity>
- fish | loot | kill | mine
- inventory <entity> [MaxSlots]
[MaxSlots] is optional and will return up to n Slots (counting from 1), (-n) minus will return last n Slots
Equipment in order: Armor feet to head, mainhand, offhand, body, saddle.
Example, compacting inventory from one chest minecart into another one:
/loot insert entity @e[limit=1,type=chest_minecart,tag=1] inventory @e[limit=1,type=chest_minecart,tag=2]
Possibilities
Concatenate
- String old + String new
- List of Strings
- Any Array
- Multiple Nbt Values (selected by nbt selector)
- Nbt Compound (only the top layer) as strings with escaped Quotes ("key":"value")
- Return result: amount of elements concatenated
given path will be replaced with new string
p.s. if given path is a string and a string is concatenated, the result is concatenation of those two strings
Math Operation
- performs math operation on the target value, target can be of any numeric type, Error will be thrown and success set to 0 when type is not numeric
- ^= stands for Power, can also be used to calculate Root
- Targeted Path number TYPE will not change
- for command syntax help install this mod client side
- Return result and success: non zero on success
Storageplayer
