Developer Case Converter
Convert between snake_case, camelCase, PascalCase, kebab-case, and CONSTANT_CASE.
The Dev Case Converter transforms text into programming naming conventions - camelCase, PascalCase, snake_case, kebab-case, CONSTANT_CASE, and more. Built for developers who need to convert variable names, function names, and identifiers between different coding styles.
What This Tool Does
Different programming languages and frameworks use different naming conventions. JavaScript uses camelCase, Python uses snake_case, CSS uses kebab-case, and constants use SCREAMING_SNAKE_CASE. Manually converting between these formats is tedious and error-prone, especially with multi-word names. This tool converts any text into the developer case format you need. It handles spaces, hyphens, underscores, and existing case boundaries correctly, producing clean identifiers ready to use in code.
Why Use This Tool
Naming conventions are fundamental to code readability, but they differ across languages, frameworks, and teams. JavaScript typically uses camelCase. Python prefers snake_case. CSS uses kebab-case. Converting a variable name from one convention to another means carefully editing case boundaries - a process that is tedious and error-prone, especially for long multi-word names. This tool handles the conversion correctly every time. It detects word boundaries from any input format and converts to your target case, saving developers from one of the most common naming chores.
How to Use
- Paste your text or variable name into the input box.
- Select the target case format - camelCase, PascalCase, snake_case, kebab-case, etc.
- Click the conversion button.
- Copy the converted result.
Common Use Cases
- Converting variable names from camelCase to snake_case for Python
- Transforming API field names between JavaScript and database conventions
- Generating CSS class names in kebab-case from descriptions
- Converting constant names to SCREAMING_SNAKE_CASE
- Creating consistent naming across different parts of a project
Example
Tips
- Paste multiple names (one per line) to batch convert all at once
- The tool detects word boundaries from camelCase, snake_case, kebab-case, and space-separated input
- Use CONSTANT_CASE (SCREAMING_SNAKE_CASE) for environment variables and configuration constants
Frequently Asked Questions
What case formats are supported?
camelCase, PascalCase, snake_case, kebab-case, CONSTANT_CASE, dot.case, path/case, and more.
Does it handle existing case boundaries?
Yes. It detects word boundaries from spaces, hyphens, underscores, and case transitions (camelCase boundaries) and converts correctly.
Is it free?
Yes, completely free with no sign-up.
Can I convert multiple lines at once?
Yes. Enter multiple names, one per line, and all will be converted.
Is my code private?
Yes. All conversion happens in your browser. No data is sent to any server.
Naming Consistency in Projects
Converting naming style in bulk helps keep APIs, database fields, and frontend props consistent across teams. Use this tool when migrating legacy code or preparing naming standards for new modules. Consistent case formats improve readability, reduce mapping errors, and simplify code review discussions.
It also shortens onboarding time for new contributors.
Predictable naming improves maintainability across codebases.
This improves long-term consistency.
