YAML is the format of choice for configuration, powering Docker Compose, Kubernetes manifests, CI pipelines, and app settings, while JSON remains the language of APIs and data storage. Our free YAML to JSON Converter moves cleanly between the two, parsing readable YAML into structured JSON or serializing JSON back into tidy YAML.
Built on the well-established js-yaml parser, this yaml converter tool correctly resolves anchors and aliases, multi-line block scalars, and comment-annotated files, so even complex configs convert accurately. Use json to yaml online to turn an API payload into a human-friendly config, or run it as a dependable yaml parser free of charge to validate and flatten deeply nested settings into JSON. Set the output indentation to 2 or 4 spaces, optionally sort keys alphabetically for consistent diffs, and convert in real time as you type, all in one yaml json tool with one-click copy and file download for JSON or YAML.
Because parsing happens entirely in your browser, your secrets, environment variables, and infrastructure files never leave your machine. Pair it with our JSON to CSV Converter to push config data into spreadsheets, switch document formats using the XML to JSON Converter, or beautify and validate the results with the JSON Formatter.
