Practical formatting guide
How to Convert Text Case Correctly
Choose text case according to where the words will appear. Normal prose usually needs sentence case, editorial headings may use Title Case, URLs normally use kebab-case and programming identifiers follow the conventions of their language.
Choose the right text case
A case converter changes capitalisation and separators, but the final choice should still follow the rules of the document, brand or codebase.
| Use | Input | Result |
|---|---|---|
| Body copy | quarterly SALES update | Quarterly sales update |
| Editorial heading | how to plan a product launch | How to Plan a Product Launch |
| JavaScript variable | customer order total | customerOrderTotal |
| Python identifier | customer order total | customer_order_total |
| URL slug | Customer Order Total | customer-order-total |
| Constant | maximum upload size | MAXIMUM_UPLOAD_SIZE |
How to convert case safely
Automatic conversion is fast, but names, acronyms and editorial title rules can require a final human check.
- Keep a copy of the original text when formatting a long document.
- Convert a representative sample before processing everything.
- Review names, abbreviations, apostrophes and words with intentional capitalisation.
- Check the destination style guide before publishing or committing code.
Writing, marketing and code
Writers should favour readable sentence case for paragraphs and follow their publication’s headline style. Marketers should keep calls to action readable instead of turning whole sentences into uppercase. Developers should match the established naming convention of the language, framework and repository.
