JSON
YAML

How to Use

Paste JSON in the left panel to convert it to YAML, or paste YAML to convert it to JSON. The conversion happens automatically as you type. Both outputs are syntax-highlighted and can be copied with a single click. The tool preserves data types, nested structures, and arrays.

Common Use Cases

  • Converting JSON API specs to YAML for OpenAPI/Swagger documentation
  • Translating Kubernetes YAML manifests to JSON for programmatic manipulation
  • Converting JSON config files to YAML for tools like Ansible or Docker Compose
  • Migrating configuration between systems that use different serialization formats

Frequently Asked Questions

Does the conversion preserve comments?

JSON does not support comments. When converting YAML to JSON, any YAML comments are lost. Converting back to YAML will not restore them.

Are all YAML features supported in JSON?

Most YAML features convert cleanly to JSON. However, YAML-specific features like anchors, aliases, and custom tags do not have JSON equivalents and may not convert as expected.

Can I convert multi-document YAML files?

The tool handles single-document YAML. If your file contains multiple documents separated by ---, split them and convert each document individually.
