About this tool
The converter handles accented letters correctly, so it works in any Latin-script language. “Sentence case” capitalizes the first letter of each sentence and “Title Case” the first letter of every word.
For developers it includes camelCase, PascalCase, snake_case, kebab-case and CONSTANT_CASE, handy for naming variables, files or keys.
