How It Works

The lowercase-to-uppercase converter uses one-to-one character transformation: - Every lowercase letter (a-z) maps to its uppercase equivalent (A-Z) - All numbers, spaces, punctuation, and special characters remain unchanged - Accented letters (é, ñ, etc.) convert to their uppercase accented forms - The process is reversible - you can convert back using the Uppercase to Lowercase tool
