What is Text Case Conversion?
Text case conversion is the process of changing the capitalization of text to different formats. This includes converting text to all uppercase, all lowercase, title case (where each word is capitalized), sentence case (where only the first letter of each sentence is capitalized), and inverse case (where the case of each character is flipped).
