If, as your subject says, you want to convert negative to positive, and vice
versa, simply put a minus sign in front of your formula, as in:

=-VLOOKUP(D53,AN54:AO4000,2,FALSE)

If, as the body of your message says, you want to convert negative to positive,
but leave the positive results as is, use:

=ABS(VLOOKUP(D53,AN54:AO4000,2,FALSE))
