Supported case formats

UPPER CASE makes everything uppercase. lower case makes everything lowercase. Title Case capitalizes the first letter of each word. Sentence case capitalizes only the first letter after periods. camelCase and PascalCase join words without separators (used in JavaScript and C# respectively). snake_case uses underscores (Python convention). kebab-case uses hyphens (common in URLs and CSS).

How to use it

Paste your text in the input area, click the case format you want, and the converted text appears below. Copy it with one click. The converter handles mixed input - it can split camelCase or snake_case text back into words before converting to another format.
