JSON to YAML Converter

Convert your JSON data to YAML format instantly. YAML is more human-readable and commonly used for configuration files, Kubernetes manifests, and CI/CD pipelines.

How to Use

  1. Paste your JSON — Paste the JSON data you want to convert into the input panel.
  2. Click Convert — The tool converts your JSON to clean, properly indented YAML.
  3. Copy the YAML — Copy the YAML output and use it in your configuration files, Kubernetes manifests, or CI/CD pipelines.

Key Features

  • Clean, human-readable YAML output with proper indentation
  • Handles nested objects, arrays, and all JSON data types
  • No reference aliases — each value is written inline for clarity
  • 120-character line width for optimal readability

Use Cases

  • Converting JSON API configs to YAML for Kubernetes deployments
  • Transforming JSON settings into YAML for CI/CD pipeline configuration (GitHub Actions, GitLab CI)
  • Creating YAML-based configuration files from JSON templates

Frequently Asked Questions

Is the YAML output valid?

Yes. The converter produces valid YAML that can be used directly in configuration files, Kubernetes manifests, and other YAML-compatible tools.

Does YAML support all JSON data types?

Yes. YAML is a superset of JSON, so all JSON data types (strings, numbers, booleans, null, arrays, objects) are fully supported.

Are comments preserved?

JSON does not support comments, so there are no comments to preserve. The output is pure YAML converted from JSON data.

Can I convert YAML back to JSON?

Not with this tool directly. PureJSON focuses on JSON-to-YAML conversion. However, since YAML is a superset of JSON, you can use a YAML parser to convert back.

Does the converter handle special characters?

Yes. Special characters in strings are properly escaped or quoted in the YAML output to maintain data integrity.
