About this case converter
Paste text and switch it to any casing with one click. Beyond the everyday transforms (uppercase, lowercase, Title Case, Sentence case), it includes the developer set: camelCase, PascalCase, snake_case, kebab-case, and CONSTANT_CASE — handling word boundaries in existing identifiers intelligently.
Sentence case respects punctuation, capitalizing after periods, question marks, and exclamation points. Accented characters convert correctly (á ↔ Á), which many tools get wrong.
FAQ
What’s the difference between camelCase and PascalCase?
camelCase starts lowercase (myVariableName); PascalCase starts uppercase (MyClassName). Conventionally, variables use camel and classes use Pascal.
Does Title Case lowercase small words?
This tool capitalizes every word, the simple convention. Editorial style guides that lowercase short words (of, the, a) vary too much to automate reliably.
Can I convert an existing camelCase name to snake_case?
Yes — the developer transforms detect word boundaries from capitals, spaces, dashes, and underscores, so myVariableName becomes my_variable_name.
