    Nominal to Numeric will do that for you, but be sure to use the "dummy coding" option and not "integer coding" if your survey answers are not actually in some kind of numerical scale rating.

    hello @Corina there are help menus + tutorial processes for all of the most common operators including Nominal to Numerical. I would strongly recommend reading the Help menu and examining the tutorial process.
