How it works
This case converter turns your text into 13 case styles as you type: six for writing, seven for code names. Change case with nothing retyped; it is a case changer, text capitalizer and mixed case generator in one.

Upper and lower case, and a Caps Lock fixer
UPPER CASE and lower case change every letter, and a few letters grow: ß becomes SS. iNVERSE cASE swaps capitals and small letters, which turns hELLO back into Hello; reverse caps does only that. For capitals that alternate, use the mocking text generator.
Code names from ordinary words
The seven code rows split your text into words at spaces, at punctuation and between a small letter and a capital, then join the words their own way. HTTPResponse code 404 becomes http_response_code_404 in snake_case and HttpResponseCode404 in PascalCase.
- March and May stay small in Sentence case, because both are ordinary words too.
- Writing Turkish or Azerbaijani? Switch Language rules in More options, so i becomes İ and I becomes ı.
Questions and answers
How do I capitalize text?
Paste it and pick a row. As a capitalization tool the page has three: Sentence case capitalizes the first letter of each sentence, Start Case the first letter of every word, and Title Case each word except short ones such as a, of and the.
What is proper case?
Proper case is another name for start case, also called initial caps: every word starts with a capital and the rest is small. It is the Start Case row. The page to capitalize each word opens on it.
Is this a camel case converter too?
Yes. The camelCase row removes the spaces and starts every word after the first with a capital: first name becomes firstName. PascalCase, or Pascal case, capitalizes the first word as well. The camel case converter opens on those two rows.
Is there a snake case converter and a kebab case converter here?
Yes, both are among the code rows. snake_case joins the words with underscores and kebab-case with hyphens, all in small letters. Apostrophes are deleted, not split on, so don’t becomes dont. The snake case converter opens on them and shows where digits split.
What is letter case?
Letter case is whether a letter is a capital (upper case) or a small letter (lower case). Mixed case uses both, as an ordinary sentence does. Digits and punctuation have no case, and the six writing rows leave them as they are.
