What this tool does
This converter rewrites your text in whichever letter case you choose. It is handy for cleaning up headings, formatting variable names in code, building slugs, or fixing text that was accidentally typed with Caps Lock on.
Case styles explained
- UPPERCASE — every letter capitalized:
HELLO WORLD - lowercase — every letter small:
hello world - Title Case — first letter of each word:
Hello World - Sentence case — first letter of each sentence:
Hello world. Bye now. - camelCase — joined words, first lowercase:
helloWorld - snake_case — words joined by underscores:
hello_world - kebab-case — words joined by hyphens:
hello-world
Common uses
- Formatting code identifiers (variables, functions, file names).
- Preparing SEO-friendly URL slugs (see our Slug Generator).
- Standardizing spreadsheet or CSV data.
Limitations
- Title Case here capitalizes every word; it does not apply editorial rules that keep words like “and” or “the” lowercase.
- camelCase, snake_case and kebab-case strip punctuation and collapse spaces, which is the usual behavior for identifiers.
