  • In the new “Conditional Formatting Rules” menu, go to the last advanced option of “Custom formula is” and apply the following formula:
    =COUNTIF($B$2:$B$15,B2)>1
  • Now you will observe the duplicate data that will be highlighted in green, as they will be marked and repeated.
  • Finally, with the cell contents highlighted in green color, you can clearly see that you might have recorded the same data twice and there are duplicate lines, you just need to delete the same data.
