Case Converter

Stays on this device. Type or paste, click any case to apply and copy. Each card previews the first 80 characters so you can spot the right conversion without trial and error.

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. The conversions strip non-alphanumeric separators (commas, slashes, etc.) and join on the case-specific joiner.

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.
