automated normalizaion to 1NF

Hi
Please have a look at automated normalization to 1NF, It's not complete though. just wanted to know if I'm going right. If somethings seems wrong, please let me know. I have to do some error handling and all. 
code refactoring/making translatable is also need to be done.  
Also, I feel the messages written by me is not very clear in various steps, need some suggestions to make them clear to users.
Hi
can we keep it below main heading. see the screenshot ? will it look good ?
