Frequently Asked Questions
Does Title Case handle small words like "in", "and", "of"?
Yes! Our Title Case engine properly keeps minor conjunctions, prepositions, and articles lowercase unless they begin a title.
How does Sentence case work?
Sentence case capitalizes the first letter of every sentence after a period, exclamation mark, or question mark, and lowercases the remainder.
Can I convert code identifiers like snake_case to camelCase?
Yes! It includes programming case transformations for developers and data analysts.
Will converting to uppercase or lowercase damage punctuation?
No, punctuation marks, numbers, and symbols are preserved completely intact while alphabetic letters are transformed.
Privacy Guarantee
Text transformations run entirely client-side.
