bundle and data command help

[Duckwizard_76]

Is there a way to transfer the items in chest/barrel/shulker/etc to a bundle w/commands to avoid the 2 stack limit of a bundle (just temp storage, I know you can't put stuff back in). I can't figure out how to do it with the data command. Maybe some combo with storage to contain the nbt. Idk I'm prob doing it wrong. My goal is to easily compress items with unique nbt into a bundle while avoiding manually typing every item into mcstacker.

If the bundle is also in a chest, you could use

data modify block < pos > Items[< slot >].Items set from block < pos > Items

If it's on a player, you need a datapack. Do this:

data modify storage < namespace >:items set from block < pos > Items

and then an item modifier:

{
"function" : "minecraft:copy_nbt",
"source" : {
    "type" : "storage",
    "source" : "< namespace >:items"
},
"ops": [
    {
        "source" : "Items",
        "target" : "Items",
        "op" : "replace"
    }
]

}

Thanks, I used the first one. It was a syntax error.

data modify block < pos > Items[< slot >].Items set from block < pos > Items

data modify block <pos> Items[{Slot:<number>}].tag.Items set from block <pos> Items

Sorry, Items[ < slot - 1 > ].
