Case Converter

Convert any block of text between six common casing styles instantly.

About this tool

Switching text between UPPERCASE, lowercase, Title Case, Sentence case, camelCase, and snake_case by hand is slow and error-prone. This tool converts a whole block instantly, which is handy for headlines, variable names, and cleaning up text pasted from inconsistent sources.

How to use it

  1. Paste your text into the input box.
  2. Click the casing style you want (upper, lower, title, sentence, camelCase, or snake_case).
  3. Copy the converted result.

Tips

  • camelCase and snake_case strip spaces and punctuation, so they're best used on short phrases or identifiers, not full sentences.
  • Title Case here capitalizes the first letter of every word — for editorial-style title casing with exceptions for small words, you may want to review the result manually.
  • Sentence case only capitalizes the first letter of each sentence, which is useful for fixing text that was typed in all caps.

FAQ

Will this fix ALL CAPS text back to normal?

Yes — use Sentence case or Title case to convert shouty text back into normal capitalization.

Does camelCase handle punctuation?

Punctuation and spaces are removed when converting to camelCase or snake_case, since neither format allows them.
