What is Text Case Inverter?

This tool inverts the case of each character in your text. Every uppercase letter becomes lowercase, and every lowercase letter becomes uppercase. Numbers and symbols are left unchanged.

For example, 'Hello World' becomes 'hELLO wORLD'. It's a quick way to fix text that was accidentally typed with Caps Lock on.
