How to Use the Text Case Converter

  1. Paste or enter your input into the text field.
  2. Configure any options (format, delimiter, encoding, or mode) using the controls above the output.
  3. The result updates instantly — no submit button required for most operations.
  4. Click Copy or Download to take the output to your next step.

Paste any block of text into the input box and pick the case style you want. Conversions run on every keystroke using the browser's native String methods, which means accented characters (é, ü, ß) and non-Latin scripts are handled correctly — German ß becomes SS in uppercase, Turkish dotted i is preserved, and combining diacritics aren't broken.

How the Text Case Converter Works

Title Case capitalises every word; Sentence case capitalises only the first letter of each sentence (after . ! or ?). camelCase, PascalCase, snake_case and kebab-case strip punctuation and join words with the chosen separator, which is handy for renaming variables or generating identifiers from prose.

Frequently Asked Questions

What's the difference between Title Case and Sentence case?

Title Case capitalises the first letter of every word — useful for headings. Sentence case only capitalises the first word of each sentence and any proper nouns you typed yourself.

Does the converter handle accented characters correctly?

Yes — it uses toLocaleUpperCase / toLocaleLowerCase, so é becomes É, ß becomes SS in uppercase, and Greek or Cyrillic letters convert as expected.

Can I convert text to camelCase or snake_case?

Yes. camelCase joins words with no separator and lowercases the first letter; snake_case and kebab-case strip punctuation and join with _ or -. Numbers and existing word boundaries are preserved.

Does Title Case know to leave 'a', 'the', 'of' lowercase?

No — this is straightforward title case that capitalises every word. Proper APA / Chicago style title casing (which lowercases short articles and prepositions) is not applied.
