Display duplicate records?

[Diane K]

I have a list of over 13000 of my customer names. Many of the customers have
the same name, but are at a different address. I need to identify those with
a duplicate name. I don't want to delete them, I just want to highlight or
otherwise identify them. Any ideas?

You can sort the data by name, so that all identical names come
together. Then it is quite easy to introduce a formula like:

=IF(OR(A2=A1,A2=A3,"Duplicate","Unique")

in a helper column in row 2, and then copy this down the column (this
assumes that names are in column A). You can then fix the values, so
the description is then tagged with the name.

If the original order of the data is important to you, then you can
put a simple sequence 1,2,3 etc down another helper column first, and
then you will be able to re-sort the data back into that order once
you have done the above.

Hope this helps.

Sorry, missed a bracket in the formula:

=IF(OR(A2=A1,A2=A3),"Duplicate","Unique")

Apologies.

Dear Diane,

You can easily extract duplicate records using Filord utility. All you need to do is to save your list as an Excel sheet, install the program and run Duplicates function. Find the details at www.filord.com

Please refrain from spamming the newsgroups by answering a question that

1. Has already been answered

2. That is over 18 months old.


Then finally the spamming by posting a link to a commercial program.
