YAML and JSON — Both Great, Different Jobs
YAML is the go-to format for configuration files — Docker Compose, GitHub Actions, Kubernetes manifests, Ansible playbooks. JSON is the standard for APIs and data interchange. This converter bridges the two, letting you switch formats instantly.
When You Need This
Migrating a config file from YAML to JSON (or vice versa)? Debugging a CI/CD pipeline and need to see the raw structure? Converting API responses to human-readable YAML for documentation? All common use cases — and this tool handles them all.
About YAML Comments
YAML supports comments (lines starting with #). JSON does not. When converting YAML to JSON, comments are stripped since there's nowhere to put them. Going the other direction, JSON to YAML, the output is clean YAML without comments.
Supported YAML Features
- Nested objects — indentation-based hierarchies
- Arrays — dash-prefixed list items
- Block scalars — multi-line strings with | and > indicators
- Inline collections — compact [array] and {object} syntax
- Data types — strings, numbers, booleans, null
