camelCase joins words together with no spaces, capitalizing the first letter of each word except the first. Example: "hello world" becomes "helloWorld". It is widely used in JavaScript and Java variable names.

snake_case joins words with underscores and uses all lowercase. Example: "hello world" becomes "hello_world". It is common in Python and database column names.

kebab-case joins words with hyphens and uses all lowercase. Example: "hello world" becomes "hello-world". It is used in CSS class names and URL slugs.

What does "alternating case" do?

Alternating case toggles between lowercase and uppercase on every character: "hello" becomes "hElLo". It is often used for humorous or emphasis purposes.

Does it handle special characters?

Yes. camelCase, snake_case, and kebab-case strip non-alphanumeric characters when joining words. Other formats preserve punctuation and symbols.

Does Title Case follow AP or Chicago style?

No. It capitalizes the first letter of every word, including short words such as "a", "of" and "the". For AP or Chicago headlines, lowercase those small words by hand after converting.

How do I change uppercase to lowercase in Word or Google Docs?

In Word, select the text and press Shift + F3 to cycle through lowercase, UPPERCASE and Capitalize Each Word. In Google Docs, use Format > Text > Capitalization. This tool also covers sentence case and the programming cases, which neither editor offers.
