When to Use a Text Case Converter
- Fix Caps Lock mistakes: open the text case converter, paste the shouting text and click Sentence Case.
- Blog headings: Title Case makes H2 and H3 headings look consistent.
- Meta descriptions: Sentence case reads naturally in search results.
- Social handles and tags: lowercase keeps usernames and hashtags uniform.
- Spreadsheets: clean up imported names and product lists before sorting.
Writing Tips for Capitalization
- Avoid long all-caps text. It is harder to read and can look like shouting.
- Keep brand names as they are. Check names like iPhone or eBay after converting.
- Re-check acronyms. Sentence case may turn "SEO" into "Seo"; fix those by hand.
- Pick one heading style. Use either title case or sentence case for all headings on a site.
