    Comparing Data Need to Include & Exclude

    What dioes E1 & E2 mean?
    Please explain.

    Try something like this:

    With your data in columns A and B

    E1: Missing (or any text other than the Col_B column title)
    E2: =COUNTIF($A$1:$A$27,B2)=0

    (Notice the dollar sign ($) plaement in the formula AND that it refers to
    the FIRST DATA ITEM in Col_B)

    C1: ListB

    Select the Col_B data from B1 to the end of the list

    From the Excel main menu:
    <data><filter><advanced filter>
    Check: Copy to another location
    List range: (your already selected Col_B data)
    Criteria Range: $E$1:$E$2
    Copy to: $C$1
    Click the [OK] button

    That will create a listing, under C1 of the Col_B items that are not in the
    Col_A list.

    Is that something you can work with?

    RE: Comparing Data Need to Include & Exclude

    The E1:E2 range is the Criteria for the Advanced Filter. Usually that means
    the first cell must be a column heading from the data list, followed by a
    list of items to be matched.

    Since we are performing a complex matching function, we can't use one of the
    column headings from the data list (eg ListA) in cell E1. A common practice
    is to leave the cell blank, but I prefer to give the criteria a somewhat
    descriptive heading. Hence "Missing". Technically, E1 can be blank or any
    value that is NOT one of the data column headings.

    Cell E2 is the key to extracting the correct data.
    The criteria formula is:
    =COUNTIF($A$1:$A$27,B2)=0

    That function begins by checking all of ListA for values that match the
    value in cell B2, which is the first data cell under the ListB column
    heading. If there are no matching items, the count is 0....so the E2 value
    equates to TRUE and the B2 value is copied to the extraction area. Since the
    first reference of the COUNTIF formula contains dollar signs, that same range
    will be used for every iteration of the formula. The second reference (B2)
    has NO dollar signs, making it a relative reference. When the Advanced
    Filter runs that reference will change for each item in ListB....First, B2,
    then B3...etc to the end of the list. All ListB items that are not on ListA
    will be copied to the extractions area under C1.

    Does that help?
