What is YAML to JSON conversion?

While YAML is popular for human-authored configuration, JSON is the standard for APIs, databases, and programmatic data exchange. Converting YAML to JSON lets you take a Kubernetes manifest, Helm values file, or GitHub Actions workflow and work with it programmatically — feed it to a REST API, store it in a document database, or pass it to a code library that expects JSON.

How to convert YAML to JSON

  1. Paste your YAML into the left pane, or drop a .yaml or .yml file.
  2. The JSON output appears instantly. Comments are stripped (JSON does not support them).
  3. Copy the formatted JSON or download it as a file.
  4. Need to go the other way? Use our JSON to YAML converter.

YAML anchors and aliases — are they supported?

Yes. The yaml package fully resolves YAML anchors (&anchorName) and aliases (*anchorName) before converting to JSON, so shared values are expanded and inlined correctly.

What happens to YAML comments?

YAML comments (# comment) are stripped during conversion because the JSON specification does not support comments. If you need to preserve documentation, consider moving it into a dedicated description key in your JSON structure.
