How to change text case online
- Paste your text into the input box.
- Click the case you need — writers use Title and Sentence case, developers use camelCase, snake_case and kebab-case.
- Copy the converted result.
Everyone hits this: a heading pasted in ALL CAPS, a CSV of names in lowercase, a variable list that needs to be snake_case for Python and camelCase for JavaScript. Retyping is error-prone; converting is instant. Title Case capitalizes every word (including after hyphens and quotes), while Sentence case only capitalizes sentence starts — pick whichever your style guide wants.
Frequently asked questions
How do I fix text typed with Caps Lock on?
Paste the text and click Sentence case — it lowercases everything and re-capitalizes the first letter of each sentence, saving you from retyping.
What's the difference between camelCase, PascalCase, snake_case and kebab-case?
They're programming naming conventions: camelCase starts lowercase (myVariableName), PascalCase capitalizes every word (MyClassName), snake_case joins lowercase words with underscores (my_variable_name), and kebab-case uses hyphens (my-css-class).
Is my text uploaded when I convert it?
No. The conversion is plain JavaScript running in your browser — your text never leaves your device.
