October 1, 2026 · 1 min read
A case converter fixes messy pasted text—shouting ALL CAPS emails, title-case headlines, or sentence case for body copy—without retyping.
Steps
- Open the case converter.
- Paste your text.
- Choose UPPER, lower, title, sentence, or other modes available in the tool.
- Copy the result into your doc or CMS.
Combine with the word counter when you also need length checks, or slug generator for URL-safe titles.
When each case helps
| Mode | Typical use |
|---|---|
| UPPER | Acronyms, legal exhibit labels |
| lower | Normalize before search/replace |
| Title Case | Headlines and product names |
| Sentence case | Body paragraphs after a CAPS paste |
Tips
- Title case rules vary by style guide—spot-check short words (a, of, the)
- Convert after removing track-changes markup so hidden characters do not linger
- For URLs, prefer a dedicated slug tool over title case alone
Limits
Mewix does not apply Chicago/APA title-case exception lists automatically. Proper nouns and brand stylizations still need a human pass.
