Common Text Case Formats
Useful context for choosing the right case conversion
Title case capitalizes important words and keeps short connector words lowercase, making it useful for page titles, article headlines, and labels.
Sentence case lowercases most text, then capitalizes the first letter after sentence-ending punctuation. It works well for paragraphs and descriptions.
Slug case converts text to lowercase words separated by hyphens, which is useful for readable URLs, filenames, CSS classes, and simple identifiers.
Uppercase and lowercase conversions are useful when cleaning pasted data, standardizing labels, formatting spreadsheet values, or normalizing imports.
