About this case converter
The case converter rewrites text into a chosen capitalisation style — sentence case, lowercase, UPPERCASE, Title Case, and developer styles such as camelCase and kebab-case. Paste the text, pick a style, and copy the converted result without retyping anything by hand.
It saves time on the small but fiddly cleanup jobs: fixing a heading typed with caps lock on, normalising a pasted list, or reshaping a label into the casing a code base expects. The chosen style is applied consistently across the whole block, including across multiple lines.
Common uses
- Fix text that was accidentally typed in all caps or all lowercase.
- Convert headings or titles into consistent Title Case before publishing.
- Turn labels or keys into camelCase or kebab-case for code and URL slugs.
Helpful tips
- Title case capitalises most words; check small words like and or of against your style guide.
- Use camelCase or kebab-case when preparing variable names, file names, or slugs.
- Paste the final text first, since editing after converting can reintroduce inconsistent casing.
