Note: This tool only supports basic YAML syntax. Complex YAML may not convert accurately.
🔄 What is YAML ↔ JSON Converter?
YAML (YAML Ain't Markup Language) and JSON (JavaScript Object Notation) are both data serialization formats with different syntax. YAML uses indentation and is human-readable, while JSON uses braces and quotes for machine processing. This tool converts between the two formats bidirectionally, useful for Docker Compose, Kubernetes, GitHub Actions config files and API response analysis.
📋 YAML vs JSON Comparison
| Aspect | YAML | JSON |
|---|---|---|
| Syntax | Indentation-based | Braces, brackets |
| Comments | # supported | Not supported |
| Quotes | Optional | Required |
| Main Use | Config files | API communication |
💡 Use Cases
- Convert Docker Compose YAML to JSON for programmatic parsing
- Convert Kubernetes manifests to JSON for API submission
- Convert JSON API responses to YAML for readable inspection
- Debug GitHub Actions workflow files
Frequently Asked Questions
Does it support complex YAML?▼
This tool supports basic YAML syntax (key-value, arrays, nested objects). Advanced features like anchors (&), aliases (*), and multiline strings (|, >) are only partially supported.
What happens to YAML comments?▼
JSON does not support comments, so YAML # comments are removed during conversion. Save important comments separately.
How does type conversion work?▼
true/false become booleans, numeric values become Numbers, null/~ become null. Wrap in quotes to keep as strings.
What is YAML to JSON Converter?
Convert between YAML and JSON formats instantly. YAML is human-readable and used in config files, while JSON is widely used in APIs. Switch between formats easily.
