    Identification of duplicate numbers and missing numbers in multiple columns

    I have a excel file (attached) consists of multiple columns with numbers from 1 to 69000. Duplication of numbers and missing numbers are to be identified and to be displayed in a new excel sheet.

    Not only like that.

    Contains the values like BBxxxx, Total-xxxx.

    OP should learn how to ask question first.

    Re: Identification of duplicate numbers and missing numbers in multiple columns

    if you can list the permitted values
    in one column,
    then COUNTIF (in the next column)
    will tell you how many times each value is found
    you can then distinguish
    0 (missing),
    1,
    and 2-or-more (duplicates)

    Re: Identification of duplicate numbers and missing numbers in multiple columns

    Here is a small example of Pat's suggestion.
    The list of all possible values is in column XFC of the Total consolidated sheet.
    Column XFD of the Total consolidated sheet is populated using: =COUNTIFS(A$1:J$10,XFC1)
    The array entered formula* to find duplicates is:
    Formula: copy to clipboard

    The array entered formula* to find missing values is:
    Formula: copy to clipboard
    Please Login or Register  to view this content.

    Array entered formulas are confirmed by pressing CTRL+SHIFT+ENTER to activate the array, not just ENTER. You will know the array is active when you see curly braces { } appear around your formula. If you do not CTRL+SHIFT+ENTER you will get an error or a clearly incorrect answer.
    Let us know if you have any questions.
