Case Converter

Fixing text case quickly and consistently

Changing the case of text by hand is slow and easy to get wrong, especially for long lists or headings. This converter handles the common jobs in one step. Use it when text was typed with Caps Lock on, when a spreadsheet column needs consistent formatting, or when headings across a document follow different styles and need to match.

Each style has its place. Sentence case capitalises only the first word and proper nouns, and it reads naturally for most headings, buttons and labels on websites and apps. Title Case capitalises the main words and keeps short ones such as 'and', 'of' and 'the' in lowercase, which suits book titles, article headlines and formal documents. UPPERCASE grabs attention but is harder to read in long passages, so keep it for short labels or warnings. Check names and abbreviations after converting, because no tool can know that an acronym like GST or a brand name should keep its own capitals.

Developers will find the programming styles useful. camelCase starts with a lowercase letter and capitalises each following word, and it is common for variables in JavaScript. PascalCase capitalises every word, including the first, and is used for class and component names. snake_case and kebab-case join words with underscores or hyphens, which suits database columns, file names and URLs. Converting a phrase directly saves time and avoids typos when you are naming many things at once. Everything happens in your browser, so you can safely paste internal documents or code. A consistent case style across a project makes it look more professional and easier to maintain.
