Solution 1:

• Ctrl+H
• Find what: \R(?=\S)
• Replace with: ,
• Replace all

Explanation:

\R     : any kind of linebreak
(?=\S) : Positive lookahead, make sure we have a non space character after, to avoid inserting a comma at the endof the string

Result for given example:

one,two,three,four,five

Solution 2:

CTRL+ H -> check "regular expression" -> search \s\r\n (or \s+ )-> replace all with ,.
