Convert JSON to YAML

YAML is easier to read and to hand-edit than JSON, which is why it dominates config files for tools like Docker Compose, Kubernetes, and CI pipelines. This converter turns a JSON object into clean, indentation-based YAML.

How to convert JSON to YAML

  1. Paste or type your JSON.
  2. The converter parses it and re-serializes the same data as YAML.
  3. Copy the YAML into your config file — keys map directly, arrays become dashed lists.

Frequently asked questions

Is YAML a superset of JSON?

Yes. Any valid JSON is also valid YAML, so the conversion is lossless. The converter simply rewrites it in YAML's more readable, indentation-based syntax.

Is my JSON sent to a server?

No. Conversion happens entirely in your browser — nothing is uploaded.

What is YAML?

YAML (YAML Ain't Markup Language) is a human-readable data serialization language. It is commonly used for configuration files and in applications where data is being stored or transmitted.

Why convert between YAML and JSON?

YAML is often preferred for human editing due to its clean syntax, while JSON is the standard for data exchange between web services. Converting between them is common when moving from configuration to API consumption.
