What are case converters?
Text case refers to whether letters are uppercase (A–Z), lowercase (a–z), or a defined combination. Different contexts require different case formats: book titles follow style guides like AP or Chicago, code identifiers follow language-specific conventions, and URLs require lowercase hyphenated slugs.
For writers and editors:Title case, sentence case, and capitalized case tools help you format headings, titles, and sentences to match your publication's style guide. Inverse case and alternating case add creative typographic options.
For developers: camelCase is standard in JavaScript and JSON; snake_case in Python, databases, and file names; PascalCase for class names and React components; kebab-case for CSS classes and URLs; SCREAMING_SNAKE_CASE for constants and environment variables; dot.case for config keys. The slug generator creates clean, SEO-friendly URL paths.
