You can use this steps-
While working with Excel and typing text into the Excel cell, you can always break the line and continue in a new row. To do so, every time you want to break a line, you would use the shortcut ALT+ENTER.
From time to time though, you might want to reverse this action, remove line breaks and go back to having only one line of text. There is quite a few ways to do so, one of them is to use Excel find/replace dialog box. Using this feature is really straightforward, the only problem is that not everyone knows how to type in the line break symbol. The trick here is to press ALT and then enter 010 using the numeric keypad.
As a result you will probably see a small blinking dot (at least that’s how it looks on my computer) in the “Find what:” field.

You can leave the “Replace with:” field empty (the line break will then be simply removed). Or alternatively enter, let’s say, a space there, to replace line break characters with spaces.
If you want to keep the original multi-line text untouched, and what you need is to have a copy of the text with removed break lines, you can use Excel function clean which removes all non-printable characters from a string. It seems to do the job
Try this AND LET ME KNOW.
