Case Convert API

Convert text between any naming convention via REST API: camelCase, snake_case, UPPER_SNAKE_CASE, kebab-case, PascalCase, Title Case, and lowercase. Essential for code generation, API response normalization, and data transformation pipelines.

How it works

POST a string and the target case format. The API parses word boundaries intelligently (handles existing camelCase, snake_case, spaces, and hyphens), then re-joins in the target format.

Use cases

• Normalize database column names to JavaScript camelCase in API responses
• Convert user-typed labels to URL-safe kebab-case slugs
• Transform JSON keys between snake_case (Python APIs) and camelCase (JS)
• Generate variable names in the correct convention during code generation
