Why Convert YAML to JSON?
YAML is popular for configuration files (Docker Compose, Kubernetes, GitHub Actions) because of its readability. JSON is required by many APIs, data stores and programming libraries. This converter bridges the gap — paste any valid YAML and get standards-compliant, pretty-printed JSON instantly.
YAML vs JSON — Key Differences
| Feature | YAML | JSON |
|---|---|---|
| Syntax | Indentation-based | Brace/bracket-based |
| Comments | Supported (#) | Not supported |
| Readability | Human-friendly | Machine-friendly |
| Multi-line strings | Native (| and >) | Escaped \n |
| Data types | Auto-detected | Explicit |
Tips
YAML is whitespace-sensitive — use consistent 2-space indentation. Tabs are not allowed in YAML. Comments (lines starting with #) are stripped during conversion since JSON does not support them.
