VBA Arrays - Check strict (not approximative) match

Question

If UBound(Filter(myArray, Sheets(i).Cells(1, j).Value, True)) = -1 Then
 \'take action
End if

I used this syntax to compare an element found in Cel

Answer 1

If the array is only used for this comparison and not needed for anything else you could also force full word comparisons by adding your own delimiters that never appear in the data - maybe square brackets.
So if you change your array to contain "[mally]", "[kate]", "[becks]"
then your condition becomes:

If UBound(Filter(myArray, "[" & Sheets(i).Cells(1, j).Value & "]", True)) = -1
