Text Case Converter — 10 Formats

Our case converter supports 10 different text case formats, covering everything from simple uppercase/lowercase transformations to developer-oriented formats like camelCase and snake_case.

Available Formats Explained

• UPPERCASE: All letters converted to capital — used for headings, acronyms, emphasis.
• lowercase: All letters in small case — useful for normalizing data, email addresses, URLs.
• Title Case: First letter of each word capitalized — standard for titles, headings, proper names.
• Sentence case: Only the first letter of each sentence is capitalized — natural writing format.
• camelCase: No spaces, first word lowercase, subsequent words capitalized — standard in JavaScript, Java variable names.
• PascalCase: Like camelCase but first word also capitalized — used for class names in most OOP languages.
• snake_case: Words joined by underscores, all lowercase — Python variables, database column names, file names.
• kebab-case: Words joined by hyphens — URL slugs, CSS class names, HTML attributes.
• Alternating case: Alternates between upper and lower case for stylistic or fun purposes.
• Inverse case: Flips the case of every letter — fun transformation for design or obfuscation.
