What is JSON to YAML Tool?

JSON to YAML Tool converts JSON data into YAML format. It is useful when you want to turn JSON into a configuration-friendly format or review the same data in a more YAML-like structure.

The tool converts input in real time and lets you control whether strings are quoted and whether keys are sorted. That makes it useful for preparing or reviewing configuration-oriented output.

How to Use

1. Paste JSON data into the input area.
2. Review the YAML output.
3. Toggle quotes or key sorting if needed.
4. Use the result once it matches your target format.

If the JSON is invalid, the tool shows an error instead of YAML output.

Main Settings

With Quotes

This wraps string values in quotation marks. It is useful when you want to make string values more explicit, especially if they could otherwise look like numbers or special values.

Sort Keys

This outputs keys in alphabetical order. It helps when you want a more consistent layout for reviews, diffs, or shared configuration files.

Use Cases

• Converting JSON-based settings into YAML
• Reviewing API data in YAML form
• Drafting Kubernetes or Docker Compose style configuration
• Comparing how quoting and key order affect the final output

Input and Output Example

{
  "name": "John",
  "enabled": true,
  "ports": [3000, 3001]
}

An input like this becomes YAML such as:

name: John
enabled: true
ports:
  - 3000
  - 3001

Things to Keep in Mind

• Before using the output directly, it is still worth checking whether it matches the exact format expected by the target system
• Quotes can change how values look and may affect how you want to read or share the file
• If you enable key sorting, the order will no longer match the original JSON
