Data in Excel is not wrapping within cell consistently
 

I have a large spreadsheet of text data. The data has been manipulated
through cut and paste from other cells etc (originally imported from
microsoft word tables). Each cell has multiple line breaks. Within some
cells, some of the text is wrapped and some isn't. I have cleared the
wrapping format and then re-done it but these sentences etc continue to run
on past the column border. Is there any way I can make it all wrap correctly
without doing it manually?
