Text Case Converter
Instantly transform your text into any case — uppercase, lowercase, title case, sentence case, camelCase, snake_case, or kebab-case. Great for coding, writing, and data cleanup.
When is this useful?
Developers convert variable names between camelCase, snake_case, and kebab-case. Writers fix accidental caps-lock typing or format headlines into Title Case. Everything runs locally — paste sensitive text without worry.
The case styles explained
- UPPERCASE / lowercase: every letter forced to one case — for emphasis or normalizing data.
- Title Case: the first letter of every word capitalized — for headlines and titles.
- Sentence case: only the first letter of each sentence capitalized — for normal prose.
- camelCase: words joined, each after the first capitalized — common for JavaScript variables.
- snake_case: words joined by underscores, all lowercase — common in Python and databases.
- kebab-case: words joined by hyphens — common for URLs, CSS classes, and file names.
Who uses it
Programmers switch identifiers between naming conventions when moving code between languages or matching a style guide. Writers and editors fix text that came in all caps, or turn a rough phrase into a clean headline. Data folks normalize messy spreadsheet text into a consistent case. Because the tool runs entirely in your browser, you can paste code, client copy, or private notes without any of it being uploaded.
