How to delete string END at end of each cell array?

I have cellarray of size 9*23. At the end of each file, I have END as the ending row. I tried to use textscan to remove the string END but it didn't. I have end row different for each file so I can't use endrow = ...? Could you anyone told me how to do it in a loop?

Can you give a short example of exactly what you have and what you want done? E.g., is the string 'END' one of your cell elements, or what?
