Automatically link columns between imported Excel sheets


My team and I got a few Excel sheets that we want to import into; some of each sheet’s columns contain information from the other sheets (i.e. they are “linked columns”), but monday doesn’t seem to support this feature without having to manually link each item one by one (which due to the amount of items included in every sheet is totaly unfeasible), so I was wondering if I could get any input on how to achieve this via the monday API or in any other way.
