What is YAML to JSON Converter?

YAML to JSON Converter is a tool for turning YAML data into JSON. It is useful when you want to inspect configuration data or prepare JSON for API-related work.

The conversion happens in real time, and you can switch the output indentation.

How to Use

1. Enter your YAML data.
2. Choose the JSON indentation style.
3. Review the converted JSON in the result area.

If the YAML is invalid, the tool shows an error message.

Main Settings

Indent

• 2 spaces
• 4 spaces
• Minified

Use 2 or 4 spaces for readability, or choose Minified when you want a compact one-line JSON result.

Input and Output Example

name: John
age: 30
skills:
  - JavaScript
  - Python

This kind of YAML becomes:

{
  "name": "John",
  "age": 30,
  "skills": [
    "JavaScript",
    "Python"
  ]
}

Use Cases

• Reviewing YAML configuration as JSON
• Preparing JSON for API testing
• Comparing settings used in Kubernetes or CI/CD workflows
• Switching data format while keeping the same structure

Things to Keep in Mind

• Invalid YAML indentation or syntax prevents conversion
• Comments in YAML are not preserved in JSON output
• In minified mode, whitespace and line breaks are removed
