Frequently Asked Questions
What's the difference between Title Case and Sentence case?
Title Case capitalizes the first letter of each word, while Sentence case only capitalizes the first letter of each sentence. Title Case is used for headings, Sentence case for regular text.
When should I use camelCase vs snake_case?
camelCase is common in JavaScript, Java, and C#. snake_case is preferred in Python, Ruby, and database naming. Each programming language has its own conventions.
Can I convert multiple lines at once?
Yes! You can paste multiple lines of text and the converter will apply the selected case format to each line while preserving the line structure.
Are special characters and numbers preserved?
Yes, special characters, numbers, and punctuation marks are preserved exactly as they are. Only alphabetic characters are affected by case conversion.
