I have a large sheet A from which I only want to work with a subset of columns sorted in a different order in a sheet B. I can import data dynamically from A to B with ={Data!S:S} (for column S). However I would like the data to be imported the other way around too.
Is this possible to achieve?
you would create an infinite circular dependency paradox. google sheets does not work like this. only one of your two sheets can be dependant on the other one. so if sheet A is your full dataset and sheet B is "extraction of certain columns from your sheet A dataset", then if you edit your sheet A your sheet B will instantly reflect those changes. the other way around would break the formula and it would introduce mentioned circular dependency
