How can I insert a comma between 456 email addresses in excel

[patty]

I have one column in my spreadsheet of email addresses. I can paste them
into a word document, but I need to put a comma between each one in order to
email a group of addresses? Any idea how I can do that without adding 456
commas? Thank you for your help. Patty

Find and replace the paragraph mark or manual line break with a comma.
