🚀 What Is String Case Conversion?

String case conversion transforms text between different naming conventions commonly used in programming:

  • camelCase - first word lowercase, subsequent words capitalized (e.g., "helloWorld")
  • PascalCase - each word capitalized (e.g., "HelloWorld")
  • snake_case - words lowercase separated by underscores (e.g., "hello_world")
  • kebab-case - words lowercase separated by hyphens (e.g., "hello-world")
  • SCREAMING_SNAKE - all uppercase with underscores (e.g., "HELLO_WORLD")
  • Train-Case - each word capitalized with hyphens (e.g., "Hello-World")
  • dot.case - words lowercase separated by dots (e.g., "hello.world")
