Case converter — developer notes

Tokenizes on non-alphanumeric separators and camel/Pascal boundaries, then rejoins for the target case. No transliteration (café stays café).

How conversion works

Paste an identifier, pick the target case, Convert. Digits stay attached to the preceding letter run (foo2Bar → foo2 + Bar). Empty input → explicit error.

Options

Target case

camel, Pascal, snake, SCREAMING_SNAKE, or kebab — changes the output for real.

Examples

snake → Pascal

Input

foo_bar-baz

Output

FooBarBaz

camel → SCREAMING

Input

foo2Bar

Output

FOO2_BAR

Case converter FAQ

Identifiers

How is this different from Slugify?

Slugify builds URL slugs (separators, accents). This tool converts identifier case without diacritic stripping.

Title Case / dot.case?

Out of scope for v1 — only camel, Pascal, snake, SCREAMING_SNAKE, kebab.

Empty input?

Returns an empty error — never a silent success.

Are accents stripped?

No — caféBar keeps café inside the token.

Which scripts are supported?

Tokenization targets Latin letters (A–Z and Latin Extended, e.g. café). Non-Latin scripts (CJK, etc.) do not form tokens and may yield an empty error.
