About text case
Case converter switches your text between seven styles with one click: UPPERCASE and lowercase, Title Case (every word capitalised), Sentence case (only the first letter of each sentence), and the programmer-friendly camelCase, snake_case and kebab-case. You can apply them in sequence — running lowercase first and then Title Case, for instance — to clean up inconsistent capitalisation in headings, identifiers or pasted text.
There's no practical length limit, so it handles everything from a single word to a long document. The conversion runs entirely in your browser, which means nothing you type is uploaded or stored — your text stays on your device.
