Hello,
the data in the two sheets is not formatted consistently. The Address Number is text on one sheet and numbers on the other. the Address Street has trailing spaces in some rows. This needs to be taken into consideration when constructing a formula.
In N2
Copy down. note that the first match is for row 7. Before that, no match is found and the formula returns N/A. This can be fixed but will make the formula even longer.
You could use conditional formatting to format N/A values with white text on white background instead.
In O2 and copied down:
The formulas work on the assumption that each Address exists only once. If there are several records for the same address, you'd need a different approach.
cheers,
