Runs in your browser — your text and files never leave your device.
Pick a case and the whole text converts as you type. Useful for headings, code identifiers, spreadsheet columns and tidy lists.
How to use it
- Paste your text into the first box.
- Choose the case you want from the buttons above.
- Copy the converted text with the copy button.
Good to know
- camelCase, PascalCase, snake_case and kebab-case split on spaces, punctuation and existing capital letters, so "userName" becomes "user_name".
- Title Case capitalises each word; Sentence case lowercases everything and then capitalises the start of each sentence.

Frequently asked questions
Does the converter change my original text?
No. Your text stays as you pasted it; the converted version appears in the second box, and that is what you copy.
Does it handle accented letters?
Yes — accented letters are converted, and text in other alphabets is left alone rather than mangled.
