Common use cases

  • Rename a variable across naming convention boundaries — paste camelCase, grab snake_case for Python.
  • Convert a blog post title into a URL-friendly kebab-case slug in one click.
  • Translate a TypeScript interface name (PascalCase) into a CSS class (kebab-case) or a config key (snake_case).
  • Format a list of column headers from a spreadsheet (Title Case) into database field names (snake_case).
  • Normalize identifiers from third-party APIs or legacy code before refactoring.

Frequently asked questions

How does it handle camelCase or PascalCase input?
The converter splits camelCase and PascalCase boundaries before reformatting — so `helloWorld` and `HelloWorld` both produce the word list [hello, world], which is then reassembled into whichever target case you want.
What about input with underscores, hyphens, or dots?
Underscores, hyphens, and dots are all treated as word separators — just like spaces. `hello_world`, `hello-world`, and `hello.world` all produce the same result.
Is my text uploaded anywhere?
No. All conversion happens in your browser using plain JavaScript. Nothing is sent to a server.
What's the difference between snake_case and SCREAMING_SNAKE_CASE?
Both use underscores between words. snake_case uses all lowercase — common for Python variables and database columns. SCREAMING_SNAKE_CASE is all uppercase — conventional for constants and environment variable names.
What's dot.case used for?
dot.case (period-separated lowercase words) appears in configuration keys (e.g. `server.port`), Java package names, and some logging frameworks. It's less common than snake_case or kebab-case but useful when colons and hyphens are reserved by the surrounding syntax.
