"\n" matches a newline character.
\n Escaped character. Matches a LINE FEED character (char code 10). \s Whitespace. Matches any whitespace character (spaces, tabs, line breaks).
In Notepad++ press Ctr+H to open the “Find and Replace” window. Under Search Mode: choose “Regular expression” and then check the “matches newline” checkbox.
Using Regex to find and replace text in Notepad++ In all examples, use select Find and Replace (Ctrl + H) to replace all the matches with the desired string or (no string). And also ensure the 'Regular expression' radio button is set.
Notepad++ can do that comfortably, you don't even need regexes
In the find dialogue box look in the bottom left and switch your search mode to Extended which allows \n etc.
As odds on you're working on a file in windows format you'll be looking for \r\n (carriage return, newline)
a\r\nb\r\nc Will find the pattern over three lines
