What Case Converter does
Converts text between seven cases, including the four programmers actually need for identifiers.
The two most useful in practice are Title Case for headings and Sentence case for rescuing text that arrived shouting. The camel, kebab and snake options exist because turning a human label into an identifier is a job people do constantly and by hand.
The seven cases
| UPPER CASE | Everything capitalised |
|---|---|
| lower case | Everything lowercase |
| Title Case | First Letter Of Each Word — headings |
| Sentence case | First letter only — fixing text that arrived in caps |
| camelCase | JavaScript and Java identifiers |
| kebab-case | URLs, CSS class names, file names |
| snake_case | Python identifiers, database columns |
Detailed steps
- Paste your text.
- Pick the case you want.
- Copy the result.
Worth knowing
Title Case capitalises every word, which is not what most style guides actually want — they leave short words like "and", "of" and "the" lowercase unless they start the phrase. For a headline going somewhere that matters, expect to fix a few small words by hand afterwards.
Frequently Asked Questions
Title Case capitalised words that should stay lowercase.
It capitalises every word by design, which is simple and predictable. Most style guides keep articles, short conjunctions and short prepositions lowercase in the middle of a title. Convert first, then lowercase the handful of small words — quicker than doing the whole line by hand.
Which case do I need for a URL?
kebab-case: lowercase words joined by hyphens. It is what search engines and humans both read most easily, and it avoids the encoding problems spaces and underscores cause. The Slug Generator does this specifically for URLs.
What is the difference between camelCase and snake_case?
Convention rather than capability. JavaScript, Java and C# use camelCase for variables; Python and SQL generally use snake_case. Pick whichever your codebase already uses — consistency beats preference.
Does it handle accented characters?
Yes. Accents are preserved and case-converted correctly, so é becomes É and back again rather than being stripped or mangled.
Is Case Converter free?
Yes. The Vootkit free plan includes 5 tool runs a day. Upgrade to Vootkit Pro for unlimited daily use, an ad-free workspace and saved workflows.
