Formatting note
Title and sentence capitalization can vary by editorial style. Review proper names, acronyms and intentionally capitalized brand terms after automatic conversion.
Which text case should you use?
Use uppercase sparingly for short labels or identifiers, lowercase when a system requires normalized text, and sentence case for most interface labels and ordinary prose. Title case is common for English headings, but publications differ on whether short articles and prepositions are capitalized.
Developers commonly use camelCase for JavaScript variables, snake_case for database fields or Python identifiers, and kebab-case for readable web slugs and CSS class names. Always follow the naming rules of the language, framework or organization receiving the text.
Worked example
Starting with Quarterly Revenue Report 2026, camelCase produces quarterlyRevenueReport2026, snake_case produces quarterly_revenue_report_2026, and kebab-case produces quarterly-revenue-report-2026. The word, character and line counters describe the original input so you can check length before copying.
What automatic conversion cannot know
The tool cannot reliably infer names such as iPhone, eBay or OpenAI, distinguish an acronym from an ordinary word, or apply every editorial style guide. Punctuation, apostrophes, hyphens and non-Latin scripts may also need manual review. Keep a copy of important source text before replacing it in a document or codebase.
