Case Converter Suite
Professional Text Formatting Assistant
One box, six ways to change the case of your text
Text arrives in the wrong case all the time: a headline copied in capitals, a paragraph typed with caps lock on, a list in lowercase that should be capitalized. The Case Converter Suite covers the six most-requested transformations in one place, and it shows all of them side by side after each conversion so you can pick the one that reads best.
Walking through it
- Type or paste text into Input Text, or use Paste. The header counts characters, words and sentences as you edit.
- Select a mode card: Sentence Case, lowercase, UPPERCASE, Title Case, Capitalize Word or Toggle Case.
- Click Convert Text Now.
- The main result appears under a badge naming the mode. Use Copy Result or Download .TXT for it.
- Scroll to All Case Variations to see every mode's output, each with its own small copy icon.
What each mode does
- Sentence Case lowercases everything, then capitalizes the first letter of the text and the first letter after each period, exclamation mark or question mark.
- lowercase and UPPERCASE change every letter.
- Title Case capitalizes each word except short ones such as a, an, and, but, for, in, of, on, or, the, to and via, unless they come first or last.
- Capitalize Word gives every word a capital, small words included.
- Toggle Case swaps each letter's case, so capitals become small and small become capital.
Use it for
- Repairing an all-caps email subject or article headline.
- Making blog post titles and slide headings consistent.
- Normalizing imported data before it goes into a spreadsheet or database.
- Preparing slide headings or newsletter subject lines in one consistent style before publishing them.
Caveats
The converter has no dictionary, so sentence case will lowercase the pronoun I and proper nouns, and abbreviations followed by a period can trigger a false sentence start. Title case splits on single spaces and does not follow any one style guide's full rules. Text is trimmed of leading and trailing whitespace before conversion, and changing the input hides the previous result until you convert again. You can switch modes and press the convert button again without retyping, and the variations grid refreshes each time. All of the conversion is done by JavaScript on the page itself.
