About this tool
Transform any string between nine common casing formats used in writing and programming: uppercase, lowercase, title case, sentence case, camelCase, PascalCase, snake_case, kebab-case, and CONSTANT_CASE.
Features
- Nine casing presets in one panel
- One-click conversion with instant preview
- Works on multi-line text and code identifiers
- Copy result with a single button
How to use
- Paste text: Enter the phrase, heading, or identifier you want to convert.
- Pick a format: Click the button for the target case style.
- Copy output: Use the copy button to grab the converted string.
Examples
- Rename variables from snake_case to camelCase in refactors
- Normalize blog post titles to title case
- Generate CONSTANT_CASE environment variable names
- Convert kebab-case URLs to PascalCase class names
Limitations
- Title case capitalizes each word; it is not a linguistic title-case engine
- Mixed-language strings may produce unexpected word boundaries
- The text entered in the tool is processed directly in your browser and is not sent to a server.
FAQ
- What is sentence case?
- Only the first character of the entire string is capitalized; the rest stays as typed (typically lowercase).
- How does camelCase handle spaces?
- Spaces and punctuation are removed; each word after the first is capitalized and joined without separators.
- Can I convert multiple lines at once?
- Yes. Each line is processed according to the selected format rules.
