How to convert uppercase to sentence case
Text case is a formatting operation, not a reversible measurement. Punctuation and capitalization can be lost. Title and sentence case use simple English-oriented rules, not editorial rules for names or acronyms.
Worked examples
Apply the target formatting rule to the input text. Identifier styles separate letter/digit words, join them, and apply capitalization or separators. Lowercase and uppercase retain existing spacing and punctuation.
HELLO WORLD → Hello world
The output is read-only because formatting is lossy. Copy the result or swap styles to start another transformation.
