About Case Converter

Natural-language cases

UPPERCASE, lowercase, Title Case and Sentence case are for prose — headlines, labels and copy.

Programming cases

camelCase and PascalCase are common for variables and types; snake_case and CONSTANT_CASE for Python and constants; kebab-case for URLs, CSS classes and file names.

Smart word splitting

The converter detects word boundaries from spaces, underscores, hyphens and camelCase humps, so you can convert from any style to any other.

Frequently asked questions

Can it convert from camelCase to snake_case?

Yes — it splits on capital letters and separators, so any input style converts to any output style.

What's the difference between Title and Sentence case?

Title Case capitalises every word; Sentence case capitalises only the first word of each sentence.

Can I copy just one result?

Yes — each case has its own Copy button.
