About the Text Case Converter

Retyping text just to fix its capitalization wastes time. This converter changes the case of any text in one click: UPPERCASE for headings, lowercase for normalizing data, Title Case for titles, and Sentence case for text accidentally typed with caps lock on. Developers can also convert phrases to the naming styles used in code: camelCase, PascalCase, snake_case, kebab-case and CONSTANT_CASE. Letter case rules follow your selected language, for example for accented letters.

How to use it

  1. Type or paste your text into the box.
  2. Click the case you want. The text is converted in place.
  3. Apply another case at any time, or edit the text directly.
  4. Copy the result when you are happy with it.

Frequently asked questions

What is the difference between Title Case and Sentence case?

Title Case capitalizes the first letter of every word (“The Quick Brown Fox”). Sentence case capitalizes only the first letter of each sentence (“The quick brown fox”).

What are camelCase, snake_case and kebab-case?

They are ways of writing several words without spaces, used for names in programming and URLs: camelCase joins words with capitals (myVariableName), snake_case uses underscores (my_variable_name) and kebab-case uses hyphens (my-variable-name).

Does it work with languages other than English?

Yes, for every language that has upper and lower case letters, including accented Latin letters, Greek and Cyrillic. Scripts without letter case, such as Arabic and Chinese, are left unchanged.
