About this tool
Instantly transform text into any letter case — UPPERCASE, lowercase, Title Case, Sentence case, or the programmer cases like camelCase, PascalCase, snake_case, kebab-case and CONSTANT_CASE. Everything runs locally in your browser, so even sensitive text never leaves your device.
Frequently asked questions
What is camelCase versus snake_case?
camelCase joins words with no spaces and capitalises each word after the first (myVariableName); snake_case joins them with underscores in lowercase (my_variable_name). Both are common in programming.
