About the YAML to JSON Converter

This free online tool allows you to quickly and easily convert YAML (YAML Ain't Markup Language) data structures into the equivalent JSON (JavaScript Object Notation) format. Simply paste your YAML code, upload a file, or use the sample data to see the conversion in action.

Why Convert YAML to JSON?

While YAML is often favored for its human readability, especially in configuration files, JSON is widely used for data interchange on the web, particularly with APIs and JavaScript applications. Converting YAML to JSON allows you to:

  • Use YAML data in applications that primarily consume JSON.
  • Transmit configuration data via web APIs.
  • Easily parse the data within JavaScript environments.
  • Leverage the vast ecosystem of JSON tools and libraries.

How to Use This Tool

  • Paste your YAML data directly into the input editor on the left.
  • Alternatively, click "Open YAML File..." to browse and upload a .yaml or .yml file from your computer.
  • Click the "Convert to JSON" button.
  • The resulting JSON data will appear in the output editor on the right, automatically formatted for readability.
  • If there are errors in your YAML syntax, an error message will be displayed.
  • Use the "Copy JSON" or "Download JSON" buttons to save the output.

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