Frequently asked questions
What does Sentence case do?
It lowercases everything, then capitalises the first letter of each sentence.
How is Title Case decided?
It capitalises the first letter of every word. It doesn't skip small words like 'and', so tweak the output if a strict style is required.
What's the difference between snake and kebab case?
snake_case joins words with underscores; kebab-case joins them with hyphens. Both lowercase the text.
