YAML to JSON Converter - Convert YAML ⇄ JSON Online

YAML (YAML Ain't Markup Language) and JSON (JavaScript Object Notation) are both data serialization formats used for configuration files and data exchange.

YAML Characteristics:

• Human-readable: Uses indentation instead of brackets
• Comments supported: Lines starting with # are comments
• Popular in DevOps: Kubernetes, Docker Compose, Ansible, GitHub Actions
• Flexible: Supports complex data structures, anchors, references

JSON Characteristics:

• Machine-readable: Uses braces and brackets for structure
• No comments: Pure data format without comment support
• Popular in APIs: REST APIs, web applications, configuration
• Strict syntax: Requires quotes around keys and string values

Common Use Cases:

• Kubernetes: Convert YAML manifests to JSON for programmatic manipulation
• Docker Compose: Convert docker-compose.yml to JSON for parsing
• CI/CD Pipelines: Convert GitHub Actions, GitLab CI, CircleCI configs
• Configuration Management: Ansible playbooks, Helm charts
• API Testing: Convert YAML test fixtures to JSON for APIs

Client-side conversion: All YAML/JSON conversion is performed locally in your browser using the js-yaml library. No configuration data is sent to any server. Your data remains completely private.
