Case converter: uppercase, lowercase and title case

Change text to uppercase, lowercase, sentence case or title case without retyping it, and sort any list in alphabetical order.

For code and URLs

Accents stay on capital letters: “café” becomes “CAFÉ”. Everything happens in your browser; your text is never sent or saved.

Convert text to uppercase or lowercase

Paste your text and click a conversion: it changes right away, with nothing to retype. You can chain several conversions, and the Undo button takes you back. Here’s what each one does:

ConversionResult
UPPERCASETHE LORD OF THE RINGS
lowercasethe lord of the rings
Sentence caseThe lord of the rings
Title CaseThe Lord of the Rings
Capitalized CaseThe Lord Of The Rings
iNVERSEtHE LORD OF THE RINGS
aLtErNaTiNgtHe LoRd Of ThE rInGs

The counter under the text shows characters, words and lines. A “Remove accents” button turns “café” into “cafe”, and accents stay in place in every other conversion.

Title case: which words get a capital?

Title case capitalizes the main words of a title and leaves short small words in lowercase. The Title Case button follows the rule shared by AP and APA style:

  • Always capitalized: the first and last word, the first word after a colon, and every noun, verb, adjective, adverb and pronoun, even short ones such as “Is” or “It”.
  • Words of four letters or more: capitalized, including “With”, “From” and “Over”.
  • Lowercase: articles (a, an, the), short conjunctions (and, but, or, nor) and short prepositions (at, by, for, in, of, on, to).
  • Hyphenated words: each part gets a capital, except small words, as in “State-of-the-Art”.

Style guides differ on a few details. Chicago, for example, has its own rule for prepositions, so check your guide if a publisher requires one. Acronyms such as NASA stay in capitals when the option is checked.

Sentence case vs title case

StyleExample
Sentence caseHow to write a good headline
Title caseHow to Write a Good Headline

Sentence case capitalizes only the first word and proper nouns. It’s easy to read and common in web interfaces and many news sites. Title case looks more formal and suits book titles, headlines and report headings. Whichever you pick, use the same one throughout a document.

Fix text typed with caps lock on

  • Caps lock left on: “hELLO jOHN” becomes “Hello John” with iNVERSE.
  • Text all in capitals: Sentence case makes it readable in one click. The word “I” gets its capital back, but you’ll need to restore other proper nouns yourself.
  • Acronyms: the option keeps NASA or the FBI in normal text. It applies to words of 2 to 6 letters surrounded by lowercase. In text that’s all in capitals, nothing tells an acronym apart, so everything goes to lowercase.

Change case in Word, Excel and Google Docs

  • Word: select the text and press Shift + F3. Each press moves to the next case.
  • Excel and Google Sheets: =UPPER(A1), =LOWER(A1) and =PROPER(A1), which capitalizes every word.
  • Google Docs: select the text, then choose Format, Text, Capitalization.

Sort a list in alphabetical order

The Alphabetical order tab sorts a list as you type. Paste one item per line, or items separated by commas. Capitals and accents don’t throw off the order, and numbers follow their natural order: “item 2” comes before “item 10”.

Options remove duplicates, ignore a leading “a”, “an” or “the”, or sort by the last word, which is handy for alphabetizing by last name. You can also sort from Z to A or by length, and copy the result one per line, with commas or numbered. In Excel, sorting is on the Data tab, and in Word it’s on the Home tab.

camelCase, snake_case and kebab-case

These formats join several words without spaces. They’re used in programming and in web addresses. The tool removes accents and punctuation, line by line.

FormatUsed for
camelCase: lastNameVariables in JavaScript or Java
PascalCase: LastNameClasses and components
snake_case: last_namePython and databases
kebab-case: last-nameWeb addresses and CSS

How do I convert text to uppercase?

Paste your text into the tool, click UPPERCASE, then click “Copy text”. Accents stay in place, so “café” becomes “CAFÉ”.

Paste the text and click lowercase, or Sentence case to keep a capital at the start of each sentence. There’s nothing to retype.

Title case is a capitalization style for titles and headlines. The main words get a capital, while articles, short conjunctions and short prepositions stay in lowercase, as in “The Lord of the Rings”.

Sentence case capitalizes only the first word and proper nouns: “How to write a good headline”. Title case capitalizes the main words: “How to Write a Good Headline”.

Printers once kept their metal type in two cases. Capitals sat in the upper case and small letters in the lower case, within easier reach because they were used more often.

Open the Alphabetical order tab and paste your list: it’s sorted right away. Choose the order and format, remove duplicates if needed, then copy the result.

Check “Sort by last word (last name)” in the Alphabetical order tab. A list of full names is then sorted by the final word of each line.

No. The conversion runs in your browser, so your text is never sent or stored. The tool is free and needs no sign-up.
