Tips & Tricks

✓Use Title Case for headlines and headings to keep formatting consistent.
✓Apply Sentence case when cleaning up text pasted from all-caps sources.
✓For programming naming conventions like camelCase or snake_case, you'll need a dedicated code-formatting tool — this converter doesn't include those.
✓Copy the converted text right away, since clicking a different case button overwrites the current result.
