Why there's no upload step
Case conversion happens entirely in your browser with plain string logic — there's no reason for your text to touch a server for this, so it never does.
Questions
Is my text sent anywhere?+
No. Conversion happens entirely in your browser.
How does camelCase/snake_case handle existing separators?+
It splits on spaces, hyphens, underscores, and camelCase word boundaries first, then rejoins in the target style — so "hello-world" and "helloWorld" both convert correctly.
Does Sentence case handle multiple sentences?+
Yes — each sentence ending in ., !, or ? gets its own capital letter.
