FAQ

How does screaming snake case differ from regular snake_case?

SCREAMING_SNAKE_CASE uses ALL UPPERCASE letters with underscores, while snake_case uses lowercase. Both separate words with underscores, but screaming snake case is typically used for constants and environment variables.

What input formats can be converted to SCREAMING_SNAKE_CASE?

Converts camelCase, PascalCase, kebab-case, regular spaces, and mixed formats. For example: 'myVariableName' becomes 'MY_VARIABLE_NAME', 'api-key-value' becomes 'API_KEY_VALUE'.

Can I use this MCP tool to batch convert variable names in my code?

Yes, AI agents like Claude Code and Cursor can use this tool to convert multiple variable names at once. Especially useful when refactoring code to follow screaming snake case conventions for constants.

How are numbers and special characters handled in the conversion?

Numbers are preserved in their original positions. Special characters (except hyphens and underscores) are typically removed or converted to underscores, depending on context.

What's the REST API format for converting text to screaming snake case?

Send a GET request to /v1/case/screaming-snake with your text as a parameter. The API returns the converted SCREAMING_SNAKE_CASE string in the response.
