You typed a whole paragraph with Caps Lock on. Or you need "quarterly sales report draft" as quarterlySalesReportDraft for a variable name, quarterly-sales-report-draft for a URL, and "Quarterly Sales Report Draft" for a heading. Retyping is silly.

| Case | Example | Used for |
|---|---|---|
| UPPER CASE | QUARTERLY SALES REPORT | Acronyms, warnings, short labels |
| lower case | quarterly sales report | Tags, email addresses |
| Title Case | Quarterly Sales Report | Headlines |
| Sentence case | Quarterly sales report | UI buttons, body headings |
| camelCase | quarterlySalesReport | JavaScript variables |
| PascalCase | QuarterlySalesReport | Class and component names |
| snake_case | quarterly_sales_report | Python, database columns |
| kebab-case | quarterly-sales-report | URLs, CSS classes, file names |
Title Case vs Sentence case
Style guides differ:
- Title Case capitalises major words: How to Convert a PDF to Word. Common in US headlines.
- Sentence case capitalises only the first word and proper nouns: How to convert a PDF to Word. Common in UK publications and app interfaces (Google and Apple use it widely).
Pick one and use it consistently across a site.
Tips
- Caps Lock accident: paste, copy Sentence case, then fix proper nouns like names and places.
- Clean URLs: kebab-case gives readable, SEO-friendly slugs. Remove words like "a" and "the" first.
- Database columns: snake_case avoids quoting issues in SQL.
- Spreadsheets: Excel has
=UPPER(),=LOWER()and=PROPER()for whole columns.
