About This Tool
Parses YAML into JSON. Supports single-document and multi-document streams (selectable via `document_index`).
All YAML scalars are resolved to JSON types: ints, floats, booleans, nulls, and strings. Anchors and aliases are expanded inline.
Why Use This Tool
- CI pipelines — Parse GitHub Actions / GitLab CI YAML programmatically
- Kubernetes manifests — Load YAML manifests into JSON-native tools
- Config normalization — Convert YAML configs to JSON for APIs that prefer JSON
- Validation — Run JSON-schema validation against YAML sources
Frequently Asked Questions
Multi-document YAML?
Separate documents with `---`. Use `document_index` to select which one to parse.
Are anchors and aliases supported?
Yes — references are expanded inline.
What about dates?
YAML date/time tags are emitted as ISO-8601 strings in JSON.
