Case Converter
Paste your text, pick a case, and it converts instantly — right in the box below.
Everything is converted locally in your browser. camelCase, PascalCase, snake_case, and kebab-case treat each run of letters/numbers as one word, so punctuation and spacing in the original text are ignored for those four.
About this tool
Case Converter changes the capital letters in a piece of text in one click. Turn a block of capitals into normal sentences, make a heading Title Case, or force everything to lowercase before you paste it somewhere else.
It saves the tedious job of retyping text that was typed with Caps Lock on, or tidying a list of names or headings.
How to use it
- Paste or type your text into the box.
- Choose the style you want: UPPERCASE, lowercase, Title Case or Sentence case.
- Check the converted text.
- Copy the result and paste it where you need it.
Example
A friend sends you a long paragraph written entirely in capitals. Paste it in, choose Sentence case, and you get normal sentences that start with a capital letter. Then quickly fix any names or abbreviations that should stay in capitals.
Tips
- After converting to Sentence case or Title Case, scan for names, places and abbreviations such as NASA or JAMB, which may need their capitals put back.
- Title Case rules vary between style guides. Check the small words (a, of, the) if you are following a particular style.
