What is the difference between camelCase and PascalCase?

Only the first letter: camelCase starts lowercase (userName), PascalCase uppercase (UserName). Languages differ in convention — Java methods vs .NET classes, for example.

When should I use kebab-case?

URLs, file names, CSS classes and HTML data attributes. Spaces are illegal or awkward there, and search engines treat hyphens as word separators.

How are acronyms handled?

Conventions disagree: XMLHttpRequest-style acronyms may become xml-http-request or xmlh-ttp-request depending on the splitter. Check the output for acronyms and normalise your input if needed.

What it is and when to use it

Convert a string into every naming convention you run into day to day: camelCase, PascalCase, snake_case, CONSTANT_CASE, kebab-case and more, all from one input. Ideal when an API field becomes a database column becomes a CSS class and each layer demands its own style.

Changes case in bulk and converts between naming styles such as camelCase, snake_case and kebab-case — a time saver for API fields and constants.
