I have 16 numbers that have to be formatted as text to display in Excel. What can I do to check for duplicates when they are all in the same column?

    Hi @Kimberly

    66983-demo.png

    In B2 (and copy down):
    =SUMPRODUCT(--(A$2:A$17=A2)) > 1

    NB: Be carreful with SUMPRODUCT, avoid something like:
    =SUMPRODUCT(--(A:A=A2)) > 1

    @Kimberly
    Please refer to Lz-3068‘s answer.

    In addition, I would provide another formula based on Lz-3068‘s sample.
    You may add an auxiliary column, enter the formula in B2 to mark the repeated text.
    =IF(COUNTIF(A:A,A2&"*")>1,"Repeated"," ")

    Then you can use Filter to select duplicate rows.
