Ctrl-J doesn't always work. Found this method in an old thread that works very well:
Use CHAR(10) for a line break though.
The simplest way (though with a large spreadsheet, it may still not be simple) is to insert a blank column next to cells containing line breaks. In that column (say, column B), enter
B1: =SUBSTITUTE(A1,CHAR(13),"")
or
B1: =SUBSTITUTE(A1,CHAR(13)," ")
depending on whether you want to keep a space between the end of one line and the beginning of another.
Copy down as far as required. Select the column. Copy it. Select the original column. Choose Edit/Paste Special, selecting the Values radio button.
Delete the column you inserted.
