What it does
Paste text and press a button to see it in another case. You can fix a heading typed in capitals by mistake, turn a title into Title Case, make sentences start with capital letters, or turn a phrase into the style programmers use for names: camelCase, PascalCase, snake_case, CONSTANT_CASE and kebab-case. The result appears under the box and you copy it with one press.
Your text never leaves your device. If you need to count the result, open word counter, and to remove stray spaces and line breaks first use text cleaner.
How to use it
- Type or paste your text.
- Press the case you want. The result shows below.
- Press Copy the result, or Use result as my text to keep working on it, for example to try another case on top.
What each case does
- UPPER CASE and lower case: every letter big or small.
- Title Case: each word starts with a capital, except small words (a, an, and, of, the, to …) in the middle. The first and last word and the word after a colon always get a capital.
- Sentence case: the first letter of each sentence is a capital and the rest small. The word “I” is kept as a capital.
- camelCase and PascalCase: words joined with no spaces, with capitals marking each new word. camelCase starts small, PascalCase starts big.
- snake_case, CONSTANT_CASE, kebab-case: words joined by an underscore or hyphen.
- aLtErNaTe: letters switch between small and big, just for fun.
Worked example
“the lord of the rings: a tale” becomes “The Lord of the Rings: A Tale” in Title Case, “the_lord_of_the_rings_a_tale” in snake_case, and “theLordOfTheRingsATale” in camelCase.
FAQs
Does it handle names like McDonald? Title Case writes the rest of each word in small letters, so you may need to fix such names by hand.
Does it work for other languages? Yes for scripts that have capitals, such as accented European letters. Scripts without capitals, such as Hindi or Arabic, are left as they are.
Is anything sent to a server? No.
Where the numbers come from
- Title Case keeps small words such as a, an, the, of and in lower case unless they start or end the title, a common style rule. Different style guides differ slightly; check yours.
