What is Case Conversion?

Case conversion transforms text between different naming conventions used in programming. Each convention has specific rules for word separation and capitalization, and different languages and contexts favor different styles.

  • All case conversions appear simultaneously in a grid
  • Click Copy on any card to copy that specific format

Common Use Cases

  • Converting variable names between JavaScript (camelCase) and Python (snake_case)
  • Generating CSS class names (kebab-case) from design specs
  • Creating environment variable names (CONSTANT_CASE)
  • Converting between API field naming conventions

Tips

  • kebab-case: CSS classes, URL slugs
  • CONSTANT_CASE: environment variables, constants

FAQs

What is the convention for each case style?

camelCase: first word lowercase, subsequent words capitalized (JavaScript variables). PascalCase: all words capitalized (class names). snake_case: lowercase with underscores (Python, Ruby). kebab-case: lowercase with hyphens (CSS, URLs). CONSTANT_CASE: uppercase with underscores (constants).

When should I use camelCase vs snake_case?

Use camelCase for JavaScript/TypeScript variables and functions. Use snake_case for Python, Ruby, and database columns. Use PascalCase for class names and React components. Follow the conventions of your language and team.

How does the converter detect word boundaries?

The converter detects boundaries at spaces, hyphens, underscores, and transitions between lowercase and uppercase letters (camelCase splits). This means "myVariableName" correctly splits into ["my", "Variable", "Name"].

Does case conversion work with Unicode characters?

Yes. The converter handles Unicode letters including accented characters (é, ñ, ü). However, some edge cases with locale-specific casing (e.g. Turkish İ/i) may not be handled in all conversions.

What is dot.case used for?

dot.case (lowercase with dots) is used in Java package names, configuration keys (e.g. spring.datasource.url), and some file naming conventions.
