Tips
- Accidentally typed with Caps Lock on? Paste the text and click Sentence case.
- Making a URL slug? kebab-case is a quick start — or use the URL Slug Generator, which also removes accents and stop words.
- Title Case capitalises each word; style guides differ on small words like “of” and “the”, so give important headlines a final check.
