YAML vs TOML vs JSON
| Feature | YAML | TOML | JSON |
|---|---|---|---|
| Comments | Yes | Yes | No |
| Human-readable | ★★★★★ | ★★★★☆ | ★★★☆☆ |
| Strict syntax | No | Yes | Yes |
| Used in | K8s, GitHub Actions, Docker | Cargo.toml, pyproject.toml | APIs, configs |
| Nesting | Indentation | Tables | Braces |
When to Use Each Format
- YAML — Kubernetes manifests, GitHub Actions, Ansible, Docker Compose
- TOML — Rust (Cargo.toml), Python packaging (pyproject.toml), Hugo configs
- JSON — API payloads, package.json, tsconfig.json
Common YAML Gotchas
- Indentation must be consistent (spaces only, no tabs)
- Strings with colons need quoting:
key: "value: with colon" yes/no/true/false/nullare parsed as booleans/null — quote them if you mean literal strings- Multi-line strings use
|(literal block) or>(folded block)
In Automation and DevOps
Config file conversions come up constantly in DevOps workflows — migrating from one CI system to another, or updating tool configs. This converter handles the structural translation so you only need to verify the semantics. If the YAML you're working with is a Docker Compose file specifically, the Docker Compose Generator builds one from scratch rather than converting an existing one.
