String Case Converter
Convert text between camelCase, snake_case, PascalCase, kebab-case, UPPERCASE, lowercase, and Title Case. Works entirely in your browser.
Enter any string, then choose a target case below.
Frequently Asked Questions
- No. All case conversion happens entirely in your browser using JavaScript. Your text never leaves your device and the tool works offline once the page is loaded.
- camelCase, snake_case, PascalCase, kebab-case, UPPERCASE, lowercase, and Title Case. The tool splits your input into words using spaces, hyphens, underscores, and camelCase boundaries before converting.
- The tool splits on spaces, hyphens, and underscores, plus camelCase/PascalCase transitions (for example, "parseXMLResponse" becomes the words parse, XML, Response). Runs of whitespace and mixed separators are treated as a single word boundary.
- Yes. Click the Copy button below the output to copy the converted text to your clipboard.
- Yes. Once the page is loaded, all conversion runs client-side in your browser — no network requests are made.
Use Cases
Consistent naming conventions are the backbone of maintainable code. Developers move between languages and frameworks daily, each with its own casing standard—camelCase in JavaScript, snake_case in Python, kebab-case in CSS, PascalCase in components, and SCREAMING_SNAKE_CASE for constants. A string case converter removes the friction of switching contexts by instantly reformatting identifiers to match the target convention. Teams use it to enforce style guides before code review, to align API payloads between frontend and backend services, to normalize database column names during migrations, and to format environment variables for deployment pipelines. It also helps during refactoring sprints, when renaming symbols across dozens of files must follow a single convention, and when onboarding new team members who need to adopt established naming patterns quickly. Technical writers rely on it to keep documentation, README files, and code examples consistent across an entire repository.
- Normalize variable and function names across polyglot codebases
- Convert API request and response fields to match language conventions
- Format CSS classes, HTML IDs, and JavaScript selectors consistently
- Prepare database columns, keys, and environment variables for deployment
- Align terminology in documentation, tutorials, and technical specifications
