Case Converter - Change Text Case Online (upper, lower, title, camelCase)

Different contexts demand different text cases: code uses camelCase and snake_case, headlines use Title Case, and legal documents use ALL CAPS. A case converter saves you from manual re-typing.

Supported Case Types

• lowercase - every letter becomes small
• UPPERCASE - every letter becomes capital
• Title Case - first letter of each major word capitalized
• Sentence case - only the first letter of each sentence capitalized
• camelCase - no spaces, each word after the first starts with a capital
• PascalCase - like camelCase but the first word also starts with capital
• snake_case - words separated by underscores, all lowercase
• kebab-case - words separated by hyphens, all lowercase

When to Use Each Case

• camelCase / PascalCase - JavaScript, Java, C# variable and class names
• snake_case - Python, Ruby, Rust variable names; database column names
• kebab-case - URL slugs, CSS class names, HTML data attributes
• UPPERCASE - constants in many languages (MAX_RETRIES, API_KEY)
