Case Converter
What this tool does
Paste text, press a style, and the whole thing changes at once. It is quicker than retyping a heading, and it does not disturb your paragraphs — only the letters change, so line breaks and punctuation survive exactly as they were.
The styles
- Title Case — publishing style, where short joining words stay lowercase.
- Sentence case — a capital after each full stop, the rest lowercase.
- camelCase / PascalCase — words joined up, used for variables and class names.
- snake_case / kebab-case — words joined by an underscore or hyphen, used in code and URLs.
- Inverse Case — flips every letter, which is handy when Caps Lock was left on.
