Paste text and convert it between common code and writing case styles.
About this tool
Converts text between common code and writing case styles — camelCase, PascalCase, snake_case, kebab-case, CONSTANT_CASE, Title Case, and more — detecting word boundaries from whatever format you paste in.
Frequently asked questions
How does it detect word boundaries in camelCase input?
It splits on the transition from a lowercase letter to an uppercase letter, as well as on existing separators like underscores, hyphens, and spaces — so camelCase, snake_case, or space-separated input all convert correctly to any other style.
Will it preserve acronyms like "URL" or "ID" correctly?
Consecutive uppercase letters are treated as a single word during splitting, so an acronym generally stays intact rather than being split letter-by-letter — though very unusual mixed-case input can still produce unexpected boundaries.
