you can use execute store success to compare nbt elements. it works by you copying the element you wanna compare and replacing it with another element you want to compare it with, storing the success of this action will tell you whether the nbt elements are the same or different.

i think i was not clear, i want to check if a specific item exists anywhere in a array

so kinda like
if (item in array)

[inner locust]

execute if data storage test:data some_array[{id:”minecraft:stone”}]
You mean like this?

[hallow cove]

yes but instead of writing the id i would get the id of a storage

[inner locust]

You could use macros, which would send the id through to a function and you would replace the minecraft:stone with “$(id)”

[hallow cove]

uhm i need this datapack to be compatible with minecraft 1.20.1 though

[inner locust]

Then you would need to iterate through a copy of the array and use the method above that eeyuh mentioned
