How do I delete an incorrect entry from the address book?

How do I automatically delete the double entry in my yahoo address book?

• Because it would take too long for me to delete it one by one. Is there any add-on button that I can click and then it will automatically sort my address book and delete one of the double entries in there.

• Answer:

  There are several so called applets what you can download to remove duplicate addresses in address book. Here is a site for one, what you can download for free: http://www.novell.com/coolsolutions/tools/14072.html or you can do it manually: First, export the address book to *.csv comma-separated format. From: http://office.microsoft.com/en-us/excel/HA010346261033.aspx Open the file in Excel. Select all of it. Do DATA then FILTER, then ADVANCED FILTER, then check off UNIQUE RECORDS ONLY. That will show only the unique records. Then COPY what is showing to the clipboard. Go back to DATA then FILTER then ADVANCED FILTER then Do NOT check off UNIQUE RECORDS ONLY. Then the whole file will show. Press the DELETE key to delete all the rows. Then do CTRL-V to paste in the uniquely filtered rows. Then SAVE the file, and all the duplicates will be gone. Then import the *.cxv file back into the email address book. Hope I helped....:)
