    Screening formula to flag correct zip codes

    First time poster. I have a very large data set (.5 GB) to dig through. Any recommendation on a screening technique to remove any zip codes that don't match my target? The catch: I'm on a Mac (so no VBA) and there are approx. 90+ zip codes.

    I've attached an initial draft of the document. The desired zip codes are in column L. Any help is appreciated. Thanks.

    Hello & Welcome to the Board,

    With the desired zip codes in column L and matching against the zip codes in column B, use a helped column to find the match and then filter by that helped column for a non-number and delete

    Example, column M >> =MATCH(B2,$L$3:$L$80,0)

    If there is a match this formula will return a number, if not, then #N/A

    Filter by the #N/A and delete visible rows
    HTH
    Regards, Jeff
