Which case to use? camelCase is conventional for JavaScript / TypeScript variables. PascalCase for class and component names. snake_case for Python and SQL. kebab-case for URLs, CSS classes, and most Linux config files. CONSTANT_CASE for environment variables and immutable globals.

camelCase is conventional for JavaScript / TypeScript variables (`firstName`). PascalCase for class and component names (`UserProfile`). snake_case for Python and SQL identifiers (`user_id`). kebab-case for URLs, CSS classes, and most Linux config files (`my-tool-name`). CONSTANT_CASE for environment variables (`API_KEY`). dot.case for namespaced identifiers (`com.example.tool`).

The conversions strip non-alphanumeric separators (commas, slashes, etc.) and join on the case-specific joiner. iNvErSe and aLtErNaTiNg cases are joke / sarcastic-meme styles included because people ask for them.

Common questions

Does it preserve emoji and Unicode?

Letters and digits are preserved (including most accented Latin); other Unicode (emoji, CJK, etc.) is generally stripped by the simple regex split. For Unicode-aware case conversion you need a fuller library.

Can I batch-convert from a CSV?

Not directly — paste one column at a time. For multi-column transforms, use the JSON formatter or a spreadsheet.
