About YAML/JSON Converter
YAML and JSON are both popular data serialization formats. YAML is preferred for configuration files (Kubernetes, Docker Compose, GitHub Actions) due to its readability, while JSON is the standard for APIs and data interchange. This converter transforms between the two formats instantly, preserving all data types, nested structures, and arrays.
How to Use
- Paste your YAML or JSON content.
- Click "YAML → JSON" or "JSON → YAML" to convert.
- Copy the converted output.
Key Features
- ✓ Convert YAML to JSON and JSON to YAML
- ✓ Preserve nested structures and data types
- ✓ Handle arrays, objects, and scalar values
- ✓ Validate input format before conversion
Common Use Cases
- • Converting Kubernetes manifests to JSON
- • Transforming Docker Compose files
- • Preparing YAML configs from API JSON responses
- • Migrating between YAML and JSON config formats
Frequently Asked Questions
When should I use YAML vs JSON?
Use YAML for human-edited config files (better readability with indentation). Use JSON for machine-to-machine communication, APIs, and data storage (stricter syntax, wider support).
Does conversion lose any data?
No. YAML and JSON support the same fundamental data types (strings, numbers, booleans, null, arrays, objects). The conversion is lossless.
Can YAML have comments?
Yes. YAML supports comments with #. JSON does not support comments. Comments are stripped during YAML-to-JSON conversion since JSON cannot represent them.
Does this handle multi-document YAML?
This tool converts single YAML documents. For multi-document YAML (separated by ---), convert each document separately.
