I need to filter a 2D array based on 2 columns

[leandrofeder]

Hello,

I have an API call that returns all this information (the array on the left), and it returns the description, document number, and version of this document (it returns all versions of the same document).

I need to output only the most recent version of each document.
Could you help me?

Simplest would be to use a map (if you are on LabVIEW 2020+). Iterate through your 2D array and only add the item to the map if the version is higher than the one already in the map (or if it doesn't exist yet of course). The output is just the map itself.

prior to labview 2020, you would use variant attributes

Assuming the highest version is at the top you can solve it like this:
