What is JSON to YAML converter?

JSON to YAML rewrites JSON data as YAML, the format used by Kubernetes manifests, Docker Compose, GitHub Actions, Ansible and many configuration files. YAML is easier to read and comment, and every JSON document has an exact YAML equivalent. Choose 2-space, 4-space or tab indentation; the output updates instantly and the input is validated so errors are caught before you paste YAML into a deployment.

    Copy the result into your .yml or .yaml file.

Frequently asked questions

Is YAML output always equivalent to the JSON?

Yes. YAML is a superset of JSON, so the converted document describes exactly the same data.

Which indentation should I use?

Two spaces is the convention for Kubernetes, Docker Compose and GitHub Actions. YAML does not allow tabs for indentation in most parsers, so prefer spaces.

Are strings quoted?

Only when needed — for example strings that look like numbers, booleans or contain special characters — so the YAML stays readable.
