About text case

This case converter changes the capitalisation of your text in one click — UPPERCASE, lowercase, Title Case, Sentence case, and programming styles like camelCase, PascalCase, snake_case, kebab-case and CONSTANT_CASE. It also counts characters, words and lines. It runs in your browser; nothing is uploaded.

How Case Converter works

The case styles

  • UPPERCASE / lowercase — every letter one case.
  • Title Case — first letter of each word capitalised.
  • Sentence case — first letter of each sentence capitalised.
  • camelCase / PascalCase — words joined, no spaces; camelCase starts lowercase, PascalCase starts uppercase.
  • snake_case / kebab-case / CONSTANT_CASE — words joined by underscores or hyphens, common in code.

Example

"hello world example" becomes Hello World Example (Title), helloWorldExample (camel), hello_world_example (snake) and HELLO-WORLD-EXAMPLE… (kebab uses hyphens: hello-world-example).
