About the Case Converter
Converts text into seven common casing styles at once — uppercase, lowercase, title case, sentence case, camelCase, snake_case, and kebab-case — the styles most often needed across writing and programming.
How to use it
- Enter or paste text into the Input text field.
- Read all seven casing conversions below, and copy any one with its copy button.
Formula
Each style applies a specific transformation: capitalization rules for title/sentence case, and word-boundary detection with different separators or capitalization patterns for the programming-oriented cases.
Worked example
"the quick brown fox" becomes "The Quick Brown Fox" (title case), "theQuickBrownFox" (camelCase), and "the-quick-brown-fox" (kebab-case).
Recommendations
- • camelCase and snake_case/kebab-case are common variable and file-naming conventions in programming — pick the one matching your language's style guide.
- • Title case here capitalizes every word; some style guides only capitalize major words, so check against your specific formatting requirements for formal writing.
- • Each result has its own copy button, so you can grab exactly the format you need without retyping.
Frequently asked questions
No — it applies a simple every-word-capitalized rule rather than a specific style guide's rules about minor words. Double-check against your required style guide for formal publishing.
