Choosing the Right Text Case
Sentence Case for Everyday Writing
Sentence case capitalizes only the first letter of each sentence and the pronoun "I," matching how most everyday writing is formatted. It's the safest default when pasting text that came in as all-caps or all-lowercase and needs to read naturally again.
Title Case for Headlines
Title Case capitalizes the first letter of most words, while keeping short connector words like a, the, of, and and lowercase โ unless they open or close the title. This follows the convention used by most style guides for headlines and titles.
camelCase for Code
camelCase strips out spaces and punctuation entirely, lowercases the first word, and capitalizes the first letter of every word after it. It's the standard naming convention for variables and functions in most programming languages.
Who Uses This
- Writers cleaning up text pasted from an all-caps source, like an old document or spreadsheet.
- Students formatting titles and headings consistently across an essay or report.
- Developers converting a phrase into a valid camelCase variable name.
- Social media users creating stylized aLtErNaTiNg-case captions.
A Note on Sentence Case Accuracy
Sentence case capitalizes after periods, question marks, and exclamation points, plus the standalone word "I." Abbreviations that end in a period (like "Dr." or "U.S.") may occasionally be treated as a sentence boundary โ review the result before using it in a final document.
