How do I import data from multiple fields into one with checkboxes?

I already have 1 existing simple application with just 1 table where I've entered data for a year or so.  Now, I want to import data from a survey where one of the fields ("Products") can have multiple values which I currently have done in ZoHo with checkboxes.   In Excel, the Products field is cell A1, and starting with B1 to about B10 are the possible values.  Then B11 to about B15 has the other "regular" column headers like Name, Company, Email, etc.
 
I've read a little about creating relationships in ZoHo and am familiar with the concept of relational databases, but it seems for my simple 15 field app there has got to be an easier way.  How can I import my excel or CSV data without creating a relational database or screwing up the data I have?
