Switch text between UPPERCASE, lowercase, Title Case, camelCase, snake_case, and kebab-case.
Paste text and convert it to any of seven common cases with one click — handy for renaming a variable across naming conventions, fixing accidentally-caps-locked text, or formatting a heading.
camelCase and snake_case are the two most common variable-naming conventions in code — camelCase in JavaScript, Java, and C-family languages, snake_case in Python, Ruby, and most database column names. kebab-case is standard for URLs, CSS class names, and HTML attributes. Title Case and Sentence case are for prose — headings and titles versus regular sentences. UPPERCASE and lowercase cover the simple cases, like fixing text someone sent with caps lock on.
This is a straightforward find-and-transform operation with no external calls — text never leaves your browser tab.
