Fix CAPS LOCK text, make proper headline Title Case, or turn names into camelCase, snake_case and more, all at once.
For code cases, each line is converted on its own, so you can paste a list of names or column headings.
Most case converters make you pick a target format before showing a result. This one converts your text into all thirteen formats at once — UPPERCASE, lowercase, Sentence case, headline Title Case, Capitalize Each Word, camelCase, PascalCase, snake_case, kebab-case, CONSTANT_CASE, dot.case, alternating and inverse case. Copy the one you need, or press Use to keep working on it.
camelCase starts with a lowercase letter (e.g. myVariableName) and is the standard for variables and function names in JavaScript and many other languages. PascalCase capitalizes every word including the first (e.g. MyComponentName) and is typically used for class names, types, and React components.
snake_case (words joined by underscores) is the convention in Python and many database column names. kebab-case (words joined by hyphens) is standard for CSS class names, URL slugs, and command-line flags. Neither is universally "correct" — it depends on the language or system you're writing for.
It capitalises the first letter of each sentence (after . ! ? or the Hindi ।) and of each new line, writes "I" as a capital, and lowercases the rest. Acronyms like NASA are kept unless the whole text was in capitals.
It follows the common headline style used by AP and Chicago: short words such as a, an, the, and, of, in, on, to and for stay lowercase unless they are the first or last word or come after a colon. So "the lord of the rings" becomes "The Lord of the Rings". Acronyms like NASA and brand names like iPhone are kept as they are. To capitalise every word, use "Capitalize Each Word".
Paste it and copy the Sentence case result. When the text is mostly capitals, every word is lowered first, then the first letter of each sentence and the word "I" are capitalised. Press Use to put the result back in the box and edit it further.
For UPPERCASE, lowercase, Title Case, Sentence case, and alternating case, yes — punctuation and numbers are preserved exactly. For the code cases (camelCase, PascalCase, snake_case, kebab-case, CONSTANT_CASE and dot.case), the text is split into words first, so punctuation becomes a separator. Each line is converted separately, and letters from other languages, such as é or Hindi, are kept.
