About JSON ↔ YAML Converter

This converter transforms JSON objects into clean YAML format and parses YAML back into JSON. YAML is widely used in Docker Compose files, Kubernetes manifests, GitHub Actions workflows, and configuration files because of its human-readable syntax. The converter handles nested objects, arrays, strings, numbers, booleans, and null values. When converting JSON to YAML, objects become key-value pairs with indentation, and arrays use dash notation.

Frequently Asked Questions

What YAML features does the converter support?
The converter supports the JSON-compatible subset of YAML: objects (mappings), arrays (sequences), strings, numbers, booleans, and null. This covers the vast majority of YAML used in configuration files.
Can I convert Docker Compose or Kubernetes YAML?
Yes. Paste your Docker Compose, Kubernetes manifest, or any YAML configuration file and the tool converts it to JSON. The converter handles nested structures and arrays.
Is my data safe?
All conversion runs in your browser using JavaScript. No data is sent to any server. Your configuration files and secrets stay on your device.
