What case formats are supported?

The converter supports UPPERCASE, lowercase, Title Case, Sentence case, camelCase (e.g., myVariableName), PascalCase (e.g., MyVariableName), snake_case (e.g., my_variable_name), and kebab-case (e.g., my-variable-name). These cover virtually every common use case in writing, programming, web development, and content creation.

What is the difference between camelCase and PascalCase?

Both formats combine words without spaces, but they differ in the first letter. camelCase starts with a lowercase letter (e.g., getUserById), while PascalCase starts with an uppercase letter (e.g., GetUserById). In programming, camelCase is typically used for variable and function names in JavaScript and Java, while PascalCase is used for class names, React components, and C# methods.

Does Title Case follow AP or Chicago style?

The title case conversion capitalizes major words (nouns, verbs, adjectives, adverbs) while leaving short conjunctions, articles, and prepositions in lowercase — following common AP and Chicago style conventions. Short words like "a", "an", "the", "and", "but", "or", "in", and "on" are kept lowercase unless they appear at the start of the title.

Is there a character limit?

No — there is no character limit. The case converter handles any amount of text, from a single word to multi-thousand-word articles. All processing happens instantly in your browser with no server requests, so even very long texts convert in milliseconds.
