Title case and the other case styles you keep rewriting by hand

One paste box; multiple outputs. Primary intent is Title Case; other styles sit as modes so we don’t ship six near-duplicate URLs.

When to use

Titles, renaming identifiers, cleaning CSV labels into a consistent case style.

Examples

Input
json to yaml
Output
Title: Json To Yaml · snake: json_to_yaml · kebab: json-to-yaml
Input
hello world from DEV_KIT
Output
(style-dependent)

How it works

Split on whitespace/punctuation → map per style (Title / snake / kebab / etc.). Small-word exceptions for Title Case may apply.

Common pitfalls

  • Acronyms (API, ID) may look wrong in Title Case.
  • Unicode letters need care beyond ASCII.
  • Snake/kebab aren’t reversible losslessly.

How this differs

Case styles for labels; Slugify for URL paths; Regex for custom rules.
