thumb|upright=2| A spreadsheet's concatenate ("&") function is used to assemble a complex text string—in this example, XML code for an [[SVG "circle" element.]] In formal language theory and computer programming, string concatenation is the operation of joining character strings end-to-end. For example, the concatenation of "snow" and "ball" is "snowball". In certain formalizations of concatenation theory, also called string theory, string concatenation is a primitive notion.
