Change letter case

UPPERCASE, lowercase, Title Case, camelCase, snake_case and more.

Convert text to upper case, lower case, sentence case, or any of the conventions used in programming: camelCase, PascalCase, snake_case, kebab-case and CONSTANT_CASE.

Title Case follows the usual style: short prepositions and articles stay lower case unless they open the title.

How to use it

  1. Paste the text.
  2. Choose the convention.
  3. Copy the result.

Frequently asked questions

Does it respect accents?
Yes. “ángel” becomes “ÁNGEL” and back again correctly, because the conversion uses Unicode rules rather than an ASCII table.
What does sentence case do exactly?
It lowercases everything, then capitalises the first letter of the text and whatever follows a full stop, exclamation mark or question mark.
What is CONSTANT_CASE for?
It is the convention for constants and environment variables in many languages: upper-case words joined by underscores.
