Frequently Asked Questions

What is the difference between camelCase, PascalCase and snake_case?

camelCase starts lowercase with each following word capitalized; PascalCase capitalizes every word; snake_case is all lowercase joined by underscores; kebab-case joins with hyphens. Each is common in different languages.

What is the difference between Title Case and Sentence case?

Title Case capitalizes the first letter of every word (used for headings); Sentence case capitalizes only the first letter of the whole text.

Does it support non-Latin text?

Case only applies to Latin letters, so CJK characters stay unchanged; the tool converts any Latin letters mixed in.

Are line breaks preserved?

Upper/lower/title/sentence modes preserve line breaks; identifier modes like camelCase and snake_case treat the input as a single name.
