If this is the case,

Don't take my report as definitive, only that it seems like that to me !

is there some "cost effective" way to do this in
VB or VBA/Access?

Presumably the xll functions were designed with use as cell formulas in
mind. Maybe you can take advantage of that if you have a lot to do, eg

Dim i as long
Dim arr, arrResult as Variant

qty = 10
ReDim arr(1 To qty, 1 To 1)

For i = 1 To qty
arr(i, 1) = i * 10 'populate arr
Next

Set ws = ActiveSheet

ws.Range("A1").Resize(qty).Value = arr
ws.Range("B1").Resize(qty).Formula = "=myXLL_foo(A1)"

ws.Calculate ' if calc not already automatic

arrResult = ws.Range("B1").Resize(UBound(arr)).Value
