Find value from one csv in another one (like vlookup) in bash (Linux)

Question

I have already tried all options that I found online to solve my issue but without good result.

Basically I have two csv files (pipe separated):

file1.

Answer 1

A little approach, far away to be perfect:

DELIMITER="|"

for i in $(cut -f 7 -d "${DELIMITER}" file1.csv ); 
do 
    grep "${i}" file2.csv | cut -f 3 -d "${DELIMITER}"; 
done
