Frequently Asked Questions

What text cases are supported?▾

The tool supports uppercase, lowercase, title case, sentence case, camelCase, PascalCase, snake_case, kebab-case, CONSTANT_CASE, and dot.case - covering both writing and programming conventions.

Can I convert variable names between coding formats?▾

Yes. Developers commonly use this tool to convert between camelCase, snake_case, PascalCase, and kebab-case when switching between programming languages or coding standards.

What is the difference between title case and sentence case?▾

Title case capitalizes the first letter of every significant word (e.g., 'The Quick Brown Fox'). Sentence case only capitalizes the first letter of the first word and proper nouns (e.g., 'The quick brown fox'). Title case is used for headings and titles, while sentence case is standard for body text.

When should I use CONSTANT_CASE?▾

CONSTANT_CASE (also called SCREAMING_SNAKE_CASE) is used in programming for naming constants - values that never change, like MAX_RETRIES or API_BASE_URL. It is standard practice in JavaScript, Python, Java, and most other programming languages.
