Concatenation is primarily used to combinecolumnsof data. It is a function commonly used in data manipulation to merge strings or numerical values from two or more columns into a single column. This is especially useful in data cleaning and transformation tasks where information from multiple fields needs to be represented together in a single field, such as merging first names and last names into a full name.
