Removing duplicates from excel sheet
January 7, 2004 7:12 AM   Subscribe

I'm working with an alphabetical list of email addresses in Excel, approx. 8500 addresses long. Is there any quick way to remove duplicates outside of manually scrolling through and deleting them by hand?

You didn't say what version of excel you had, try this:
assuming the data is in columns, and has column labels, select the column, then,
Data -> Filter -> Advanced Filter -> OK -> (Check) Unique Records Only -> OK

dump it to a comma-separated text file and use a perl script or similar?

er, forgot one thing, in the Advanced Filter dialog, you want to select "Copy to another location"
Filtering in-place only hides values, and doesn't remove them.

File / Save As / *.txt

$ cat file.txt | sort | uniq > newfile.txt

Nahhh, a bad spammer wouldn't bother to weed out duplicates.
