How to remove extra spaces without string concatenation?

Question

Regular Expressions

Hello!
I'm trying to write a regular expression for Notepad++ to clean the text from extra spaces.
I found such an option on the Internet. \s{2,}
It cleans spaces, but also combines all lines into one, how to avoid this?

Those. yes i have 2 lines

Стол     	    180 * 90 * 75	   1 шт   
Стул с подлокотниками 	      60 * 60 * 85	   6 шт

The controller does this

Стол 180 * 90 * 75 1 шт Стул с подлокотниками 60 * 60 * 85 6 шт

It needs to be like this

Стол 180 * 90 * 75 1 шт 
Стул с подлокотниками 60 * 60 * 85 6 шт

Answer 1

\sis any whitespace character, including the newline character.
It is enough to replace it with "" (space), and then only spaces will be replaced.
You can also specify not any whitespace character in the form \s, but a class of specific characters in square brackets. For example, spaces + tab characters. It will turn out like this:
[ \t]{2,}

Answer 2

\h{2,}
