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

I have a list of about 6000 line items. Among other things, the data

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,
