Case Converter

How to convert text case

1. Type or paste text, a variable name or a list of names (one per line).
2. Every case is generated at once. Copy the one you need.

Naming conventions by language

• JavaScript / TypeScript: camelCase variables, PascalCase classes and components.
• Python: snake_case functions and variables, PascalCase classes.
• Go: camelCase, or PascalCase to export.
• CSS and URLs: kebab-case.
• Environment variables: CONSTANT_CASE.

Frequently asked questions

When should I use camelCase, snake_case or kebab-case?

It depends on the language. JavaScript and Java use camelCase for variables and PascalCase for classes. Python and Ruby use snake_case. CSS classes, URLs and file names usually use kebab-case. Constants and environment variables use CONSTANT_CASE.

How are words detected?

Words are split on spaces, punctuation, underscores, hyphens and changes from lowercase to uppercase. Acronyms are kept together, so XMLHttpRequest becomes xml_http_request.

Can I convert many names at once?

Yes. Each line is converted separately, so you can paste a list of column names or variables and convert them all in one go.

What is a URL slug?

A slug is the readable part of a URL, such as my-first-post. It contains only lowercase letters, numbers and hyphens, with accents removed so it works everywhere.
