N-am incercat metoda ta, pentru ca deja am rezolvat cu asta. Deci cine mai are problema mea:
Open the file
Click CTRL + F
Select "Current document" in "Find in" (You can also select the folder if you have multiple files)
Search in "Source code"
Tick "Use regular expression"
Type "[\r\n]{2,}" (without quotes) in "Find"
Type "\n" (without quotes) in "Replace"
Press "Replace All"
