    leandertorres What version of Excel are you working with? If you have Excel for MS365, you could try either of the following array transformations:

     

    =LET(
    array1, A5:A8,
    array2, TOROW(B5:B8),
    HSTACK(TOCOL(IF({1}, array1, array2)), TOCOL(IF({1}, array2, array1)))
)

     

    -OR-

     

    =LET(
    arr, LAMBDA(n, CHOOSE(n, A5:A8, TOROW(B5:B8))),
    HSTACK(TOCOL(arr({1})), TOCOL(arr({2})))
)

     

    Or, if you need the ability to combine two multi-column arrays or tables:

     

    =LET(
    array1, A5:A8,
    array2, B5:B8,
    a, SEQUENCE(ROWS(array1)),
    b, SEQUENCE(, ROWS(array2)),
    HSTACK(
        CHOOSEROWS(array1, TOCOL(IF(b, a))),
        CHOOSEROWS(array2, TOCOL(IF(a, b)))
    )
)
