Convert JSON to YAML without shipping the file to a server

APIs speak JSON; many deploy configs prefer YAML. Paste JSON, get indented YAML you can drop into Compose/K8s-style files — still verify against your target tool.

chars: 50
Input
Output

When to use

Turning an API JSON sample into a starter Compose/K8s-style config, or migrating a JSON settings file you already have locally.

Examples

Input
{"replicas":3,"env":"prod"}
Output
replicas: 3
env: prod
Input
{"tags":["api","local"]}
Output
tags:
  - api
  - local

How it works

Parse JSON → dump YAML (2-space default via js-yaml or equivalent). YAML 1.1/1.2 quirks (yes/no, octals) still apply — treat output as a starting point.

Common pitfalls

  • Not always 1:1 — anchors, tags, and some number edge cases differ.
  • Validate Kubernetes/Helm output with your cluster tools.
  • Unquoted yes/no/on/off in YAML can become booleans.

How this differs

JSON→YAML here; use YAML→JSON to go back. YAML Formatter cleans YAML you already have.
