FAQ
Frequently Asked Questions
Common questions about text case conversion.
What is camelCase and when should I use it?
camelCase writes multi-word identifiers with no spaces, with each word after the first starting with a capital letter, for example, myVariableName. It is the standard naming convention in JavaScript, Java, and many other programming languages for variable and function names.
What is the difference between snake_case and kebab-case?
Both formats use all-lowercase words with a separator, but snake_case uses underscores (my_variable_name) and kebab-case uses hyphens (my-variable-name). snake_case is common in Python and database column names; kebab-case is common in CSS class names and URL slugs.
What does Title Case capitalise?
Title Case capitalises the first letter of every word. This tool applies basic title casing, every word is capitalised regardless of whether it is a short word like "a", "the", or "of". For strict AP or Chicago style title casing, additional stop-word rules would be needed.
Can I use this tool to convert code variable names?
Yes. The camelCase, PascalCase, snake_case, kebab-case, CONSTANT_CASE, and dot.case formats are designed specifically for converting natural language phrases into valid code identifiers. Special characters and punctuation are stripped automatically to produce clean results.
