YAML ↔ JSON Converter Online

Convert between YAML and JSON formats. Paste YAML to get JSON or vice versa. Free online converter.

YAML vs JSON

YAML (YAML Ain't Markup Language) uses indentation for structure and is more human-readable. JSON (JavaScript Object Notation) uses braces and brackets and is more widely supported by APIs and programming languages. Both represent the same data.

When to Use Each

Use YAML for configuration files (Docker Compose, Kubernetes, CI/CD pipelines). Use JSON for APIs, data exchange, and JavaScript/TypeScript code. Convert between them when migrating configurations or integrating systems.
