What Is a Text Case Converter?
A text case converter is a tool that transforms text between different capitalization styles. Developers use camelCase and PascalCase for variable and class names, snake_case for Python and database columns, kebab-case for CSS classes and URLs, and CONSTANT_CASE for constants and environment variables.
Writers and content creators use Title Case for headings and Sentence case for readable body text. UPPERCASE is used for acronyms and emphasis, while lowercase keeps things uniform.
CaseShift handles all of them in one place. The conversion runs entirely in your browser using JavaScript — your text is never sent to any server, so it's completely private and works even without an internet connection after the page loads.
Frequently Asked Questions
What is camelCase?
camelCase writes compound words with no spaces, where each word after the first starts with a capital letter. Example: myVariableName. It's widely used in JavaScript, Java, and Swift for variable and function names.
What is the difference between camelCase and PascalCase?
Both join words without spaces, but PascalCase (also called UpperCamelCase) capitalizes the first letter too. camelCase: myVariable — PascalCase: MyVariable. PascalCase is typically used for class names.
When should I use snake_case vs kebab-case?
snake_case uses underscores and is common in Python, Ruby, and SQL column names. kebab-case uses hyphens and is preferred for CSS class names and URL slugs, since hyphens are more readable in URLs and HTML attributes.
What is CONSTANT_CASE?
CONSTANT_CASE (also called SCREAMING_SNAKE_CASE) is all uppercase with underscores. It's used for constants and environment variables in most languages: MAX_RETRY_COUNT, DATABASE_URL.
Is my text kept private?
Yes, completely. All case conversion logic runs in your browser with JavaScript. Your text is never uploaded to any server. You can even go offline after the page loads and the tool will keep working.
Does it handle multi-line text?
Yes. CaseShift processes each line independently for most formats, preserving line breaks in the output. This is useful for converting multiple variable names or headings at once.
