Case Converter refers to the process of altering the case, structure, or arrangement of characters in a given text string. This can include converting text to uppercase, lowercase, sentence case, capitalizing words, or reversing the order of characters.
Uppercase conversion involves converting all letters in a text string to uppercase (capital letters), resulting in the text being entirely composed of capital letters.
Lowercase conversion involves converting all letters in a text string to lowercase (small letters), resulting in the text being entirely composed of small letters.
