Nested structures
Convert nested objects, arrays and scalar values while retaining data hierarchy.
Data Conversion · REST API
JSON to YAML & YAML to JSON API
Convert structured JSON into readable YAML and transform YAML documents into pretty-printed JSON through two dedicated REST endpoints.
Free tier available. Both endpoints require a JWT Bearer Token.
Conversion capabilities
Data types preserved
Maintain numeric, boolean and structured values during conversion.
Readable output
Generate readable YAML with minimal unnecessary quoting or pretty-printed JSON.
Convert JSON to YAML
Send a valid JSON document. The API generates YAML suitable for common configuration formats and parsers.
Endpoint
POST
/api/v1/convert/data/json-to-yaml
Input: application/json · Output: application/yaml
Short example
Input
{
"server": {
"port": 8080,
"compression": {
"enabled": true,
"mime-types": ["application/json", "text/html"]
}
}
}
Output

The request body must contain valid JSON. Conversion is structural only; no execution occurs.
Convert YAML to JSON
Send a valid YAML document as raw text. Objects, arrays and scalar root values are supported; the response is pretty-printed JSON.
Endpoint

/api/v1/convert/data/yaml-to-json
Input: text/plain · Output: application/json
Short example
