If this represents more than a couple people, you may want to add a "No Answer" or "Empty" row and column. Identify the type of questions that should be asked and avoid unambiguous survey questions. Crosstabulation presents the distributions of two categorical variables simultaneously, with the intersections of the categories of the variables appearing in the cells of the table.

With unordered data such as product names, you might combine into categories. This can limit the flexibility that researchers have in terms of the processes that they use.
