Text spinner for data file

This PC based program will work similar to article spinners such as "The Best Spinner", which changes words in an article to create unique content, but instead of changing text in articles it will work with a comma delimited (CSV) or excel file. Either one would work, although CSV would be preferred of the two. Bidder please let me know in your bid which one you'd prefer to work with. In the program I will have two fields where I choose the data file from my computer hard disk that I want the program to edit , and also the field name that will be modified. So for example, there's a sample file at [login to view URL] If I were to choose the field "description", it would go into the file and change around the text in the description field for each of the records. It's important that in changing the text that the description still reads well in good and proper English. It's sufficient to have approximately 50% unique text.
