How to use
- Paste your text, or load the example.
- Pick a style such as camelCase, snake_case, kebab-case or Title Case.
- Tick the per-line option to convert each line on its own.
- Copy the result, or compare it with the table of every style.
What it checks and how it works
The code styles (camel, Pascal, snake, kebab, constant, train, dot, path) use the change-case library, which splits the text into words at spaces, punctuation and changes of case, then joins them in the chosen style. UPPER and lower case use JavaScript's locale-aware case mapping. Title Case is a simplified English rule that keeps short words such as of, the and to in lower case, so it is not a replacement for a house style guide.
Arabic letters have no upper or lower case, so those styles leave them unchanged. Code styles still split Arabic text into words and join them with the chosen separator.

About this tool
kebab-case, with words joined by hyphens, is the usual choice for URL slugs. For Arabic slugs and percent-encoding, use the Arabic slug generator.
Arabic has no letter case, so UPPER, lower and Title Case leave it unchanged. The word-joining styles still split Arabic words and join them with hyphens, underscores or dots.
No. It capitalizes every word except a short list of small English words, which is close to common headline practice but not any one style guide.
