YAML to JSON Converter

YAML is the de-facto configuration format for the modern cloud-native stack — Kubernetes, Helm, Docker Compose, GitHub Actions, GitLab CI, Ansible, and OpenAPI all use it. JSON, by contrast, dominates APIs and JavaScript-based tooling. Converting between them is a daily DevOps task.

Why convert YAML to JSON?

JSON is required by many APIs, validators, and JavaScript tooling. Kubernetes accepts JSON manifests just like YAML. JSON is also easier to embed in scripts, query with jq, and post to webhooks. Converting your YAML config to JSON unlocks integrations across the entire JS ecosystem.

YAML 1.2 spec compliance

Our converter uses js-yaml, the most widely-adopted YAML parser in the JavaScript ecosystem. It supports the full YAML 1.2 specification: anchors, aliases, multi-line strings, type tags, block and flow styles.

Comments and document boundaries

YAML comments (lines starting with #) are stripped during conversion since JSON does not support them. Multi-document YAML files (separated by ---) are flattened into the first document by default — let us know if you need multi-doc array output.

Common conversion targets

• Kubernetes Deployment, Service, ConfigMap manifests
• Docker Compose service definitions
• GitHub Actions workflow files (.github/workflows/*.yml)
• Ansible playbooks and inventory files
• OpenAPI/Swagger specs (openapi.yaml → openapi.json)
• Helm chart values.yaml files
• CircleCI / GitLab CI / Travis configs
• Jekyll & Hugo front matter

Whether you're feeding a Kubernetes manifest into a JSON-only validator, embedding a Compose file in a script, or just want to read your config in a more familiar format, this tool delivers clean, ready-to-use JSON in seconds.
