    Create an array for matches of a source array to any values in a match array.

    I'm looking to identify all rows in a range that match any values from another dynamic range that can have a varying number match values. Need to get all matches to remain 0 and all non matches to go to 1. Below is the current code I am using but it does not evaluate it as single array as I was hoping.

    Below is an example of what the two input ranges would be and the output I am looking for. Thanks for the help.

    MATCH_VALUES_RANGE
    1
    2
    3

    DATA_RANGE
    1
    7
    2
    9
    3

    DESIRED ARRAY RESULT
    0
    1
    0
    1
    0

    Hi Drew- I believe this works:

    If you have duplicates in the MATCH_VALUES_RANGE, you would get numbers other than 0/1 in the result_array. If that's a problem, use this instead:

    Obviously, array-entry (CSE) is required.

    If you want an array in memory to pass on to another calculation this array entered

    will return {0;1;0;1;0}.

    To output it to the spreadsheet will require this array entered and filled down.

    If you aren’t familiar with array-entered formulas array enter means the formula must be committed from edit mode by simultaneously pressing and holding down Ctrl and Shift while hitting Enter.

    Hmmm... the countif method doesn't seem to evaluate multiple matches properly. Ended up using the following from the cross posted thread .


    {=1-ISNUMBER(MATCH(DATA_RANGE,MATCH_VALUES_RANGE,0))}

    Re: Create an array for matches of a source array to any values in a match array.

    As you may have guessed I am using this to create a dynamic list of all the "release numbers" in a table that match specific "release types" identified by another dynamic range. Below is my actual code:

    =IFERROR((INDEX(DATA_RELEASE_NUMBER,MATCH(0,COUNTIF(OFFSET(AI$2,0,0,ROW()-ROW(AI$2)),DATA_RELEASE_NUMBER)+(1-ISNUMBER(MATCH(DATA_RELEASE_TYPE,LIST_RELEASE_TYPES_TEMPORARY,0))),0))),"")

    AI$2 is the header of the list of matching "release numbers" and the list generates a dynamic range called "LIST_UNSORTED_TR_NUMBERS"
    DATA_RELEASE_TYPE is the dynamic "DATA_RANGE"
    LIST_RELEASE_TYPES_TEMPORARY the dynamic "MATCH_VALUES_RANGE"

    I am then using the following formula to sort the data Highest to Lowest to create a final dynamic range that is used for data validation, sorting, conditional formatting, etc. in various other places.

    =IF(COUNTA(LIST_UNSORTED_TR_NUMBERS)>=ROWS(AJ$2:AJ3), INDEX(LIST_UNSORTED_TR_NUMBERS, MATCH(LARGE(COUNTIF(LIST_UNSORTED_TR_NUMBERS, "<"&LIST_UNSORTED_TR_NUMBERS), ROW()-ROW(AJ$2)), COUNTIF(LIST_UNSORTED_TR_NUMBERS, "<"&LIST_UNSORTED_TR_NUMBERS), 0)), "")

    I misread the requirements, had 0 and 1 switched. This would work:
