FAQ
What’s the difference between Title Case and Sentence case?
Title Case capitalizes the main words, like a headline (small words such as “of” and “the” stay lowercase). Sentence case only capitalizes the first word of each sentence.
When should I use camelCase, snake_case or kebab-case?
They are naming styles in programming. camelCase is common in JavaScript, snake_case in Python and databases, and kebab-case in URLs and CSS class names.
Does it work with accented letters?
Yes. Letters like é, ñ and ü are converted correctly. Languages without upper and lower case, such as Korean and Japanese, stay unchanged.
