- All nine case variants appear instantly below the input — no button to click.
- Click the copy icon next to any variant to copy it to the clipboard.
Frequently asked questions
- What cases are supported?
- Nine cases in total: UPPERCASE, lowercase, Title Case, Sentence case, camelCase, PascalCase, snake_case, kebab-case, and CONSTANT_CASE. Each has its own result row with a copy button.
- How does camelCase detection work?
- The converter splits your input into individual words first, handling spaces, underscores, hyphens, and existing camelCase or PascalCase boundaries. It then reassembles the words in the target case.
- What is the difference between Title Case and Sentence case?
- Title Case capitalises the first letter of every word (Hello World). Sentence case capitalises only the first word of each sentence, as you would in normal prose (Hello world).
- What is CONSTANT_CASE used for?
- CONSTANT_CASE (also called SCREAMING_SNAKE_CASE) is the convention for naming constants in many languages — for example MY_API_KEY in JavaScript or Python.
- Is my text uploaded anywhere?
- No. All conversion happens instantly in your browser. Your text never leaves your device.
