Frequently asked questions
What is the difference between camelCase, snake_case, and kebab-case?
They join words without spaces: camelCase capitalises each word after the first (myVariableName), snake_case uses underscores (my_variable_name), and kebab-case uses hyphens (my-variable-name). They are common in code for variables, keys, and filenames.
What is Title Case versus Sentence case?
Title Case capitalises the first letter of every word (great for headings), while Sentence case capitalises only the first letter of the whole text (like a normal sentence).
Does the converter handle mixed or camelCase input?
Yes. It splits input on spaces, punctuation, and case boundaries, so “myHTMLValue” or “already_snake” are re-cased correctly into whichever format you pick.
