How to ?
 

So i have a txt file with nicknames like (vertically):

alma_taylor
aivasweet
allyson_jones
alexiaraves
chanel_sensual
alice_geller
ammie_marshall
alicia_beggs
alishakimm
ameliafitt

what i need is to have these nicknames like (horizontally):

alma_taylor,
aivasweet,allyson_jones,alexiaraves,chanel_sensual ,alice_geller,ammie_marshall,alicia_beggs,alishaki mm,ameliafitt

so basically i need them allinged vertically with a coma between each nickname. Anyone knows how to easily do it ?

Download Notepad++, paste into there. At top go to search->replace,

Find what: \r\n
Replace with: ,

and make sure Search Mode has 'extended' selected

:%s/\r\n/,/g

Microsoft Word can do this as well.
Search and Replace:
"Find What": ^p
"Replace With": ,
