Is my data safe to convert here?

Yes. js-yaml runs entirely in your browser. No data is transmitted to any server.

Does it support multi-document YAML?

Yes. Documents separated by --- are converted to a JSON array where each element is one document.

Are YAML-specific types like timestamps handled?

YAML timestamps are converted to ISO 8601 strings in the JSON output. YAML anchors and aliases are resolved before conversion.

YAML → JSON Converter

YAML Input

JSON Output

Why use a private YAML to JSON converter?

YAML config files often contain environment references, internal hostnames, or secrets. This converter processes your YAML entirely in your browser using js-yaml — no data is uploaded or transmitted.

How it works

js-yaml parses the YAML input into a JavaScript object, then JSON.stringify() serializes it to formatted JSON. Multi-document YAML (separated by ---) is converted to a JSON array of documents.

Common use cases

Converting Kubernetes manifests or Helm values to JSON for programmatic processing
Translating GitHub Actions workflow files to JSON for tooling that requires it
Converting YAML config files to JSON for APIs or services that only accept JSON
Extracting structured data from YAML documentation into JSON
