About the JSON to YAML Converter

This free online tool efficiently converts JSON (JavaScript Object Notation) data into the human-readable YAML (YAML Ain't Markup Language) format. Paste your JSON data or upload a JSON file to instantly generate the corresponding YAML structure.

Why Convert JSON to YAML?

While JSON is excellent for data interchange and machine parsing, YAML is often preferred for configuration files and situations where human readability is paramount. Converting JSON to YAML allows you to:

  • Make complex configuration data easier to read and edit by hand.
  • Use data generated by APIs (often JSON) in systems that expect YAML configuration.
  • Represent hierarchical data in a more visually structured way.
  • Leverage YAML-specific features like comments (though comments aren't generated by conversion).

How to Use This Tool

  • Paste your JSON data directly into the input editor on the left.
  • Alternatively, click "Open JSON File..." to browse and upload a .json file from your computer.
  • Click the "Convert to YAML" button.
  • The equivalent YAML data will appear in the output editor on the right, formatted with standard indentation.
  • If your input JSON is invalid, an error message will be displayed.
  • Use the "Copy YAML" or "Download YAML" buttons to save the output (as a .yaml file).

This converter uses the reliable js-yaml library directly in your browser, ensuring your data is processed securely without being sent to any server.
