Case Converter

About this case converter

Programmers constantly move names between conventions — a database column in snake_case, a JavaScript variable in camelCase, a React component in PascalCase, a CSS class in kebab-case, an environment variable in CONSTANT_CASE. Paste any text and this tool shows every common case at once, each ready to copy with one click.

Common conversions

• camelCase to snake_case (and back)
• snake_case to kebab-case for CSS or URLs
• Any case to CONSTANT_CASE for environment variables
• Title Case for headings and labels

How does it split my text into words?

Is my text sent to a server?

No. All conversion happens in your browser; your text never leaves your device.
