About the Case Converter

Switches text between eleven cases, including the programming ones - camelCase, PascalCase, snake_case, kebab-case and CONSTANT_CASE. Handy for renaming variables, tidying headings, or fixing text that arrived in ALL CAPS.

When to use each case

  • Title Case - headlines, book and article titles.
  • Sentence case - most UI text, email subjects and many news headlines.
  • camelCase - variables and functions in JavaScript, Java and C#.
  • PascalCase - class and component names.
  • snake_case - Python variables and database columns.
  • kebab-case - URLs, CSS classes and file names.
  • CONSTANT_CASE - constants and environment variables.

Fixing text that arrived in capitals

Paste text that was typed with caps lock on, or copied from a PDF in capitals, and switch it to sentence case to get readable text back in one click. Check proper nouns afterwards - no converter can know that "london" should be "London".

Turning a title into a URL? The slug generator does it properly, and the word counter shows the length as you edit.

Paste the text and press Title Case: the first letter of every word becomes a capital and the rest lower case. Copy the result with one click. Sentence case, UPPERCASE and the programming cases are one click away too.

Which cases can it convert to?+

Eleven: UPPERCASE, lowercase, Title Case, Sentence case, camelCase, PascalCase, snake_case, kebab-case, CONSTANT_CASE, aLtErNaTiNg case and reversed text.

What is the difference between camelCase and PascalCase?+

Only the first letter. camelCase starts lower (userName), PascalCase starts upper (UserName). Most languages use camelCase for variables and PascalCase for types.

Is my text uploaded anywhere?+

No. The conversion runs in your browser, so nothing you paste in ever leaves your device.
