Excel Macro that will convert phone #s

I'm needing a macro that will convert a column of 10 digit phone numbers and break them out or convert them from a XXXXXXXXXX format to a XXX XXX XXXX format.

I want to be able to copy and paste a long column of 10 digit numbers then have the macro run down the column and cut or copy the area code (first 3 digits of the 10 digit string) - move it two columns to the left - paste it into that cell - return then cut the next 3 digits - move it one column to the left, and paste it.

Much thanks in advance!
