How do I convert YAML to JSON?

Paste your YAML into the YAML editor and the JSON output appears automatically in the JSON editor. Copy it with one click.

Will comments survive the conversion?

No. JSON has no comment syntax, so YAML comments are dropped during conversion. All data — keys, values, structure — is preserved.

Is the conversion done on a server?

No. It runs locally in your browser, so your YAML is never uploaded. That makes it safe for manifests and config that contain sensitive values.

What JSON formatting do I get?

The output is pretty-printed with two-space indentation, which is readable and ready to paste into most tools or commit to a repository.

About YAML to JSON Converter

Paste YAML — a Kubernetes manifest, a CI workflow, a Compose file — and get pretty-printed JSON immediately. Everything runs in your browser, so configuration with secrets never leaves your machine.

Converting YAML to JSON is handy when an API or tool expects JSON, when you want to validate structure with strict JSON parsers, or when you need to embed config in a JSON-only context. The conversion is lossless in both directions.
