Developer Cases (The Good Stuff)

Programmers have specific needs for variable naming conventions. We support them all:

camelCase

helloWorld. Standard for JavaScript, Java, and C# variables. First word lowercase, subsequent words capitalized.

snake_case

hello_world. Standard for Python variables and database column names. Words separated by underscores.

kebab-case

hello-world. Standard for URLs (slugs) and CSS class names. Words separated by hyphens.

PascalCase

HelloWorld. Standard for Classes in most C-family languages.

CONSTANT_CASE

HELLO_WORLD. Used for defining constants in environment variables (e.g., API_KEY).

Why Use a Tool?

Consistency. Humans are bad at being consistent. If you are renaming 50 variables in a codebase, you might accidentally type `User_id` once instead of `user_id`. A tool ensures mathematical precision in the conversion.
