Case Converter
Type or paste text once, then click a button to convert it to any common case style — the input never needs retyping.
Overview
Different contexts expect different case conventions — a heading in Title Case, a JavaScript variable in camelCase, a Python variable in snake_case, a URL segment in kebab-case. Rather than converting by hand or writing a one-off script, paste text once and switch between every common case style with a click.
Examples
UPPERCASE
Hello World Example
HELLO WORLD EXAMPLE
camelCase
Hello World Example
helloWorldExample
snake_case
Hello World Example
hello_world_example
How It Works
- Paste or type your text into the box.
- Click any case button — UPPERCASE, lowercase, Title Case, Sentence case, camelCase, PascalCase, snake_case, kebab-case, or aLtErNaTiNg CaSe.
- Copy the converted result, or click another case button to try a different style from the same input.
FAQ
No. Case conversion happens entirely in your browser using JavaScript — nothing you type is transmitted anywhere.
It splits on spaces, hyphens, underscores, and camelCase capital-letter boundaries, so converting already-camelCased or snake_cased text into a different case style works as expected, not just plain sentences.
Yes — it lowercases everything, then capitalizes the first letter after each sentence-ending punctuation mark (., !, ?) as well as the very start of the text.
