How are words detected?

Words are split at underscores, hyphens, dots and spaces, at lowercase-to-uppercase humps (fooBar), and before the last capital of an acronym (XMLHttp → XML Http).

Which case should I use?

Common conventions: camelCase for JavaScript variables, PascalCase for classes and React components, snake_case for Python and SQL columns, kebab-case for URLs and CSS, CONSTANT_CASE for constants and environment variables.

Yes. Digits stay attached to the word they follow, for example address2Line → address2_line.

Can I convert many names at once?

Yes. Put each identifier on its own line and all of them are converted together.

Yes. Conversion happens in your browser and nothing is uploaded.
