The formula

Each mode applies a capitalisation rule: word-initial, all-caps, all-lower, or a join style (camel/snake/kebab).

Title Case capitalises the first letter of every word; Sentence case capitalises the first letter after sentence punctuation; camelCase joins words with no spaces and capitalises each word after the first; snake_case and kebab-case lowercase words and join them with underscores or hyphens respectively.

Frequently asked questions

Title Case capitalises the first letter of every word ("The Quick Brown Fox"). Sentence case only capitalises the first word of each sentence ("The quick brown fox").
