Renaming variables, slugifying titles, normalising CSV headers, fixing inconsistent naming in a legacy codebase — case conversion is one of those small operations you do all day. This converter shows every common case variant simultaneously: camelCase, PascalCase, snake_case, kebab-case, SCREAMING_SNAKE_CASE, Title Case, lower, UPPER. Paste once, click the variant you want.
When each case is the right one
camelCase: variables and functions in JavaScript, Java, Swift. PascalCase: classes, types, React components, file names in many TS/JS projects. snake_case: variables in Python, Ruby, Rust; database columns; YAML keys. kebab-case: URL slugs, CSS classes, HTML attributes, npm package names. SCREAMING_SNAKE_CASE: constants in most languages, environment variables. Title Case: headings and titles in English. Consistency within a codebase matters more than which one you pick — pick the convention the project already uses and stick to it.

How does it split words?
How does it split words?
On any combination of: whitespace, underscores, hyphens, or case transitions (lowercase → uppercase). So `XMLHttpRequest` splits to `XML`, `Http`, `Request`. So does `xml_http_request`. So does `xml-http-request`. Each split list then renders into every target case.
Does it handle acronyms correctly?
Does it handle acronyms correctly?
Mostly. `XMLHttpRequest` → `xml_http_request` works as expected. Edge cases (where multiple consecutive caps could be an acronym or a sequence of single-letter words) follow standard heuristics. If you have a specific convention that we get wrong, paste an example and we'll add a rule.
