Convert programming identifiers between the common naming conventions: camelCase, PascalCase, snake_case, kebab-case, CONSTANT_CASE and dot.case. Different languages and style guides prefer different formats, so you often need to rename a variable, a config key, a CSS class or a filename to match the surrounding code. This converter first splits your input into words no matter how it was originally formatted, then rebuilds it in the style you pick, so it round trips cleanly between formats. It works line by line, which makes it easy to convert a whole list of names in one go. All the conversion runs in your browser, so your code and identifiers never leave your machine.
