Frequently Asked Questions

What text case formats are supported?

Our case converter supports UPPERCASE, lowercase, Title Case, Sentence case, camelCase, PascalCase, snake_case, kebab-case, and CONSTANT_CASE. Each format has its own use cases in writing and programming.

What is camelCase used for?

camelCase (e.g., myVariableName) is the standard naming convention for variables and functions in JavaScript, Java, and many other programming languages. The first word is lowercase and each subsequent word starts with an uppercase letter.

What is the difference between Title Case and Sentence case?

Title Case capitalizes the first letter of every major word (e.g., "The Quick Brown Fox"), while Sentence case only capitalizes the first word and proper nouns (e.g., "The quick brown fox"). Title Case is used for headings; Sentence case for normal prose.
