How the case converter works
Everything is processed locally on your device — nothing is ever sent anywhere. Programmer styles (camel, Pascal, snake, kebab, constant, dot) split your text into words on whitespace, punctuation and case-boundaries (so "myXMLParser" becomes my, XML, parser), then re-join them in the chosen format. Title Case capitalises the first letter of each word; Sentence case only capitalises the first letter after a period, exclamation or question mark.
FAQ
- Is my text uploaded anywhere?
- No. All conversions happen locally on your device. Nothing is sent to a server.
- Does it support non-English text?
- Yes. UPPERCASE, lowercase, Title Case, Sentence case and inverse case work for most languages. Programmer styles (camel, snake, kebab, etc.) are designed for ASCII identifiers and may strip accents or non-Latin characters.
- What is the difference between camelCase and PascalCase?
- camelCase keeps the first word lowercase ("myVariableName"), while PascalCase capitalises every word, including the first ("MyVariableName"). PascalCase is also called UpperCamelCase.
