I have a list of about 6000 line items. Among other things, the data
includes names and email addresses. There are many duplicate entries,
checking line by line for 6000 lines is not very appealing to me.

Can someone help me to devise a formula or other way to do this?

Thanks,

--Jim

Two approaches - Filtering and Conditional Formatting


Filtering can remove the duplicates:
1. select the data
2. pull-down Data filter Advanced Filter and check unique records only


Conditional Formatting can mark the duplicates (no removal)
1. select the top cell
2. pull-down Format Condtional Formatting...then select formula is
3. for the formula use something like =COUNTIF(A$1:A$10,A1)1

Thank-you for your response. I am going to try this formula too, I want to
do what is easiest between this and the formula shown at the site Dave
linked me to. I will post back when I am done with the file.
