What is it?
The Case Converter changes the capital and small letters in your text in one tap. Choose UPPER CASE, lower case, Title Case, Sentence case, iNVERSE cASE, or styles programmers use such as camelCase, snake_case and kebab-case.
Who is it for?
Anyone who typed with Caps Lock on, writers fixing headings, students formatting titles, data-entry staff cleaning names, and programmers turning phrases into camelCase or snake_case names.
How to use it
- Type or paste your text.
- Tap the case you want. The text changes in place.
- Changed your mind? Tap Undo. Then Copy result.
Which case when?
- Sentence case: fixing text typed with Caps Lock on. Only the first letter of each sentence is capital.
- Title Case: headings and book or film titles. Short words like “a”, “of” and “the” stay small unless they come first.
- camelCase, snake_case, kebab-case: names in code, file names and URLs.
Names came out wrong
- Sentence case can’t know which words are names: “i met ravi in delhi” becomes “I met ravi in delhi”. Capitalise names by hand after converting.
- Short forms like “GST”, “PDF” or “iPhone” may change. Fix them after converting, or convert only the part you need.
- Hindi, Punjabi, Arabic and Chinese have no capital letters, so they stay the same.
