YAML is parsed and converted to JSON.
Copy or download the JSON result.
Use YAML to JSON when working with Kubernetes configs, CI/CD pipelines, or Docker Compose files that need to be programmatically processed. It is invaluable for converting YAML configuration files into JSON format for API consumption or validation against JSON schemas. DevOps teams frequently use it to transform Helm chart values and Ansible playbooks for automated tooling.
Yes, YAML anchors (&) and aliases (*) are fully resolved during conversion, producing expanded JSON with all referenced values inlined. This is particularly useful for DRY configurations where anchors reduce repetition. The tool handles nested and recursive anchor references correctly.
Yes, multi-document YAML files separated by --- are supported. Each document is converted to a separate JSON object, and the output is wrapped in an array if multiple documents are detected. This makes it easy to process Kubernetes manifests and other multi-doc YAML files.
The tool fully supports the YAML 1.2 specification, which is the current standard. It correctly handles all YAML data types including strings, numbers, booleans, null values, and timestamps. YAML 1.1 features like implicit type conversions are also handled for backward compatibility.
