Which case formats are supported?

Nine formats: UPPER, lower, Title, camelCase, PascalCase, snake_case, kebab-case, CONSTANT_CASE, and Sentence case.

How are words detected in camelCase or PascalCase?

The tool splits on spaces, underscores, hyphens, and uppercase letter boundaries, so mixed input like hello_worldFoo is handled correctly.

What is CONSTANT_CASE?

All uppercase with underscores between words, e.g. 'MAX_RETRY_COUNT'. It is the convention for constants in many languages.

How does Title case differ from Sentence case?

Title case capitalizes every word ('Hello World Foo'). Sentence case capitalizes only the first word ('Hello world foo').

Are numbers and acronyms preserved?

Numbers are kept as-is. Consecutive uppercase letters (acronyms like 'HTTP') are treated as a single word when splitting, so 'HTTPServer' → 'http_server' in snake_case.

Is my text uploaded anywhere?

No. All conversion happens locally in your browser with no server round-trip.
