Why this tool exists

Vultio Case Converter transforms any text or variable name into camelCase, PascalCase, snake_case, and kebab-case simultaneously.

Switching naming conventions is a constant chore when working across languages and frameworks. JavaScript prefers camelCase, Python favors snake_case, CSS uses kebab-case, and class names follow PascalCase — this tool handles all conversions at once.

Common use cases

Rename a database column from snake_case to a camelCase API field in one step.
Convert a CSS class name to a JavaScript variable name without typos.
Generate all four naming variants of a new feature name for consistent use across layers.
Translate human-readable labels ("user profile photo") into code-friendly identifiers.
Quickly produce consistent naming for React props, Redux actions, and REST endpoints.

Example input / output

From phrase to all cases

Input

user profile photo

Output

camelCase: userProfilePhoto
PascalCase: UserProfilePhoto
snake_case: user_profile_photo
kebab-case: user-profile-photo

From camelCase input

Input

myVariableName

Output

camelCase: myVariableName
PascalCase: MyVariableName
snake_case: my_variable_name
kebab-case: my-variable-name

Common errors

Output looks correct but has unexpected capitalisation.

Cause: The tokenizer splits on known separators. Consecutive uppercase runs (e.g. "XMLParser") may split differently than expected.

Fix: Add spaces between acronym and word ("XML Parser") before converting for predictable output.

All outputs are the same single word.

Cause: The input contained no word separators — it was treated as one token.

Fix: Add spaces, underscores, or hyphens between words, or use camelCase boundary separators in the input.

A practical convention map across JS, Python, SQL, CSS, and API schemas.
