Finding duplicates in a column with multiple product #'s

Jamie Null

Hi,

Is there a way to find duplicates when a column may contain multiple product numbers which are comma separated?  I was able to get the below formula to flag red when only one event number is duplicated in a one to one ratio, and also have the formula disregard blanks.  Any ideas if there is a way to find duplicates when your data is comma separated?

=IF([Event #]1 = 0, 0, IF(COUNTIF([Event #]:[Event #], [Event #1) > 1, 1))

Example of the data

EVENT #

Event001

Event001, Event003

Event002

Event003, Event 001

You would want to replace the criteria portion of your COUNTIF with a FIND function.

 

COUNTIFS([Event #]:[Event #], FIND([Event #]1, @cell) > 0)
