Function to create email hyperlinks for multiple cells?

I have a column with about a thousand email addresses written as plain text (one per cell obviously). Is there a way to hyperlink these without having to go through them one by one?

Thanks!

Thanks sweep, but I've already tried that.
Excel doesn't recognize the text ("[email protected]") as an email address so the hyperlink directs to "[email protected]" and not "mailto:[email protected]".
Any other suggestions?

It worked, thanks a lot sweep.
I actually did the following to only keep the address displayed as text in the cell (without the "mailto:"):
=HYPERLINK("mailto:"&A1,A1)


Just in case someone has the same problem and comes accross this topic, I also found this link:

It uses a macro, which is a more complicated way to obtain the same result. However, if there are blanks in the column (empty cells i.e. with no email addresses), this macro keeps the cells blank whereas the hyperlink function creates a "0" link (that links to "mailto:").
