JavaScript Object Notation. Universal data interchange. Strict standard; JSON5 extends it with comments, trailing commas, and unquoted keys.

Human-friendly data serialization. Used in Docker, Kubernetes, GitHub Actions, and CI/CD. Supports comments, anchors, and multi-line strings.

Tom's Obvious Minimal Language. Used in Rust (Cargo.toml), Python (pyproject.toml). Designed to be unambiguous, readable, and have clear semantics.

All conversions run entirely in your browser — no data ever leaves your device.
