Nine cases in one place
UPPER CASE, lower case, Title Case and Sentence case for writing, plus camelCase, PascalCase, snake_case, kebab-case and CONSTANT_CASE for code.
Made for variable names
The code cases split words at spaces, punctuation and existing capitals, so userID, user-id and User ID all become user_id in snake_case.
Line by line
The code cases convert each line on its own, so you can paste a whole list of names or column headers and convert them all at once.
Fix text typed in caps
Turn text typed with Caps Lock on, or an all caps headline, into normal sentence case or title case without retyping it.
Converts as you type
Pick a case and the result updates while you type or paste. Copy puts it on your clipboard in one click.
Runs in your browser

Frequently asked questions
Title case starts every word with a capital letter, like a headline: This Is Title Case. This tool capitalizes every word, including short ones like of and the, which some style guides keep in lower case.
Sentence case capitalizes only the first letter of each sentence, the way normal text is written. Names and the word I become lower case too, so check them after converting.
Ways of writing several words as one name without spaces, used in programming. camelCase joins the words with capitals (userName), snake_case with underscores (user_name), kebab-case with hyphens (user-name) and CONSTANT_CASE with underscores in capitals (USER_NAME).
camelCase starts with a lower case letter (firstName) and PascalCase with a capital (FirstName). PascalCase is common for class names, camelCase for variables and functions.
