How to Use the Case Converter
Paste your text into the input field.
Select the target case format — camelCase, PascalCase, snake_case, kebab-case, SCREAMING_SNAKE_CASE, or others.
Copy the converted output for use in your code, config, or content.
What Is Case Conversion?
Different programming languages, frameworks, and style guides use different conventions for naming variables, functions, classes, and identifiers. Case conversion transforms a string from one naming convention to another — for example, converting a human-readable label like "user profile image" into userProfileImage for JavaScript, user_profile_image for Python, UserProfileImage for a C# class, or user-profile-image for a CSS class or URL slug. Doing this manually is error-prone and tedious at scale; a case converter handles it instantly and consistently.
When to Use This Tool
Renaming variables across languages — Convert identifiers when porting code between languages with different naming conventions.
Generating code from specs or designs — Convert human-readable field names from a spec doc or Figma file into the correct case for your codebase.
Preparing API field names — APIs often use snake_case for JSON keys while frontend code uses camelCase — convert between them as needed.
Writing config files — Environment variable names typically use SCREAMING_SNAKE_CASE; convert from a readable name in one step.
