Case converter

Title case capitalises the first letter of every word, and sentence case capitalises only the first letter of each sentence. The code styles (camelCase, PascalCase, snake_case, kebab-case and CONSTANT_CASE) work line by line, so you can convert a list of names at once. Letters without case, such as Chinese or Japanese, are left unchanged.

Frequently asked questions

Does title case skip small words like “and”?

No. Every word is capitalised, so check headings that follow a style guide.

Can I convert many variable names at once?

Yes. Put one name per line and choose a code style; each line is converted separately.

Is my text sent anywhere?

No. The conversion happens in your browser.
