Case Converter
What are these case styles used for?
Different programming languages and style guides favor different naming conventions: JavaScript typically uses camelCase for variables, Python and databases often use snake_case, URLs and CSS classes commonly use kebab-case, and environment variables use CONSTANT_CASE.
When would I use this?
- Converting a variable or field name to match a different language's naming convention.
- Turning a sentence or title into a valid identifier for code.
- Quickly generating multiple case variants of the same word or phrase.
How it works
Your input is split into individual words — detecting spaces, hyphens, underscores, and camelCase boundaries — then reassembled into each target case style using JavaScript, entirely in your browser.
