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.
