Frequently Asked Questions
What's the difference between Title Case and Sentence case?
Title Case capitalizes the first letter of every word (Hello World). Sentence case capitalizes only the first letter of each sentence (Hello world. How are you?).
When should I use camelCase vs snake_case?
camelCase (helloWorld) is standard in JavaScript, Java, and C#. snake_case (hello_world) is preferred in Python, Ruby, and database column names.
Does it work with non-English text?
Yes. All case conversions work with accented characters (é, ü, ñ), Chinese characters, Japanese, Arabic, and any Unicode text.
Is my data stored or sent anywhere?
