Case Converter

Transform text into uppercase, lowercase, title case, sentence case, camelCase, PascalCase, snake_case, kebab-case and CONSTANT_CASE — instantly, with one click per format.

Examples

Input · camelCase

hello world

Output

helloWorld

How it works

Paste your text, click a case, and the output updates as you type. The words stay the same; only the capital letters and the characters between words change.

The nine cases, using “hello big world” as the input
Case	Result	Common use
UPPERCASE	HELLO BIG WORLD	Short labels and acronyms
lowercase	hello big world	Normalising text before comparing it
Title Case	Hello Big World	Headings and titles
Sentence case	Hello big world	Fixing text that arrived in all caps
camelCase	helloBigWorld	JavaScript and Java variables, JSON keys
PascalCase	HelloBigWorld	Class and component names
snake_case	hello_big_world	Python variables, database columns
kebab-case	hello-big-world	URLs and CSS classes
CONSTANT_CASE	HELLO_BIG_WORLD	Constants and environment variables

The five programmer cases keep only English letters and numbers. Punctuation and accented letters act as word breaks and are removed, so “don’t stop” becomes don_t_stop in snake_case.

Frequently asked questions

Does title case follow style rules?

It capitalises the first letter of each word, a simple and widely used approach. It does not lowercase minor words like "of" or "the".

How do I change all caps to normal sentence case?

Paste the text and click Sentence case. Everything is lowercased, then the first letter of each sentence is capitalised. Names and acronyms need fixing by hand, because the tool cannot know which words are proper nouns.

What is the difference between camelCase and PascalCase?

Both join words with no separator. camelCase starts with a lowercase letter (userName); PascalCase capitalises the first letter too (UserName).

How do I convert a paragraph to all caps?

Paste the paragraph, click UPPERCASE and copy the result. Nothing is uploaded; the conversion runs in your browser.
