Case Converter

Developers constantly switch between naming conventions: camelCase for JavaScript variables, snake_case for Python and database columns, PascalCase for class names, kebab-case for CSS classes and URLs, and CONSTANT_CASE for environment variables. Manually converting between these formats is tedious and error-prone.

This case converter intelligently tokenizes your input — whether it is camelCase, separated by spaces, underscores, or hyphens — and reconstructs it in your target format. It also handles standard text transformations like UPPERCASE, lowercase, Title Case, and Sentence case.

All processing happens locally in your browser. This is especially important when converting variable names from proprietary codebases, where sending code fragments to external services could expose internal naming patterns.

How to Use the Case Converter

  1. Paste or type text into the input editor.
  2. Click one of the nine conversion buttons (UPPER, lower, Title, camelCase, snake_case, etc.).
  3. Review the converted output in the right editor.
  4. Copy the result to use in your code or documents.

Frequently Asked Questions

  • Can it convert from camelCase to snake_case directly?

    Yes. The tool intelligently detects word boundaries in any naming convention and can convert between all supported formats in a single click.

  • Does it handle multi-line text?

    Yes. Each line is converted independently, making it easy to batch-convert variable lists or config files.

  • Is the text sent to a server?

    No. All case conversion logic runs locally in your browser.
