What is it?
A case converter transforms text between the most common naming conventions: UPPERCASE, lowercase, Title Case, Sentence case, camelCase, PascalCase, snake_case, kebab-case and CONSTANT_CASE. Each convention encodes a different meaning - Title Case for headlines, kebab-case for URLs, snake_case for Python and database columns, camelCase for JavaScript variables, PascalCase for class names, CONSTANT_CASE for compile-time constants.
When to use it
Reach for it whenever you're moving text between contexts with different naming rules: an editor pasting a CMS headline, a developer renaming variables when porting from Python to JavaScript, a marketer normalising product names for slugs and ad copy, or a data engineer reformatting CSV headers. Also useful for one-shot clean-up of all-caps email subject lines and Title Case fields entered inconsistently across an org.
Common mistakes
Don't lossy-convert acronyms: 'NASA' becomes 'Nasa' in plain Title Case and that's usually wrong. Title-case rules differ between AP, Chicago and MLA - most automated tools (including this one) follow AP and lowercase short function words; verify against your house style. When converting to snake_case or kebab-case, watch for non-ASCII characters: many systems require ASCII-only identifiers, so a transliteration step is often needed.
FAQ
- What is title case?
- Title case capitalizes the first letter of every major word. We follow AP style and leave articles, conjunctions and short prepositions in lowercase unless they're first or last.
