De nada is a common expression in Spanish that is used in response to a "thank you" to convey "you're welcome" or "it's nothing." However, there are several other synonyms used in different Spanish-speaking countries that are just as common. For example, in Mexico, "con gusto" is commonly used, which translates to "with pleasure." In Argentina, "no hay de que" and "no hay problema" are commonly used, which translates to "there's no need to thank me" and "no problem." Colombians often use "a la orden" which translates to "at your service," and in Chile, "pase nomás" is used, which translates to "just go ahead."".
