# **YAML to JSON Converter**

Convert YAML data to JSON

**YAML data**

**JSON data**

Read-only

## What is YAML to JSON Converter?

YAML to JSON Converter turns YAML data into JSON. Use it to inspect configuration files or API data in JSON form.

## How to Use

1. Paste YAML data into the input.
2. Review the JSON result.
3. Change the JSON indentation as needed.

## Main Settings

### JSON Indentation

Choose the indentation width for the JSON output. Use 2 or 4 for review, or Minify for JSON on a single line.

## Input and Output Example

```yaml
name: Taro
age: 30
skills:
  - JavaScript
  - Python
```

This YAML becomes the following JSON.

```json
{
  "name": "Taro",
  "age": 30,
  "skills": [
    "JavaScript",
    "Python"
  ]
}
```

## Use Cases

- Reviewing YAML settings as JSON
- Converting data for API tests
- Looking at Kubernetes or CI/CD settings in another format
- Switching data formats while keeping the structure

## Things to Keep in Mind

- `**yes**`, `**no**`, `**on**`, and `**off**` are treated as strings, not booleans
- Dates are treated as strings
- Comments are not preserved in JSON
- YAML with multiple documents cannot be converted
- YAML with circular references cannot be converted to JSON
