All Case Formats Explained
The tool handles every case style you will ever need:
- UPPERCASE — ALL CAPS. Use sparingly: for short headings, warnings, or emphasis. Full paragraphs in caps feel like shouting.
- lowercase — all small letters. Useful for normalizing data, file names, and case-insensitive comparisons.
- Title Case — Every Word Capitalized. The standard for blog titles, book names, and headlines.
- Sentence case — Only the first word capitalized. Normal sentence writing; perfect for fixing ALL-CAPS accidents.
- camelCase — eachWordCapitalizedExceptFirst. The standard for JavaScript variable names.
- snake_case — words_separated_by_underscores. Popular in Python and databases.
- kebab-case — words-separated-by-hyphens. Used in URLs and CSS classes.

Uppercase vs Lowercase: Quick Rules
Use UPPERCASE only for short bursts — headings, buttons, abbreviations. Long uppercase text is harder to read and looks aggressive. For body text, sentence case or lowercase is always the safer choice. When in doubt, convert to sentence case first, then apply Title Case to headings.
