## Overview (en)

Camel Snake Kebab Case converts a phrase or existing identifier into a programming naming style: camelCase, snake_case, kebab-case, PascalCase or CONSTANT_CASE. It splits words at spaces, punctuation and lowercase-to-uppercase boundaries, so userName and user-name are both recognized, then lowercases the parts and rejoins them in the chosen style. Letters and digits from any script are kept.

## Questions (en)

### How do I convert camelCase to snake\_case?

Paste the camelCase name and choose snake case as the Naming style. A break is inserted wherever a lowercase letter or digit is followed by a capital, so userAccountId becomes user_account_id.

### Can I convert a list of variable names at once?

Not as separate names. Line breaks are treated like any other separator, so the whole input becomes one long identifier. Convert one name at a time to get individual results.

### Why does XMLParser become xmlparser instead of xml\_parser?

A run of capitals is not split apart, because breaks are added only where a lowercase letter or digit meets a capital. Add a space or underscore between the parts, such as XML Parser, to get xml_parser.
