JSON to YAML Converter
Convert JSON documents to clean YAML for configs, CI pipelines and Kubernetes manifests. Handles nested objects, arrays, strings and numbers correctly.
What the tool does
YAML is the human-friendly config format behind Docker Compose, GitHub Actions and Kubernetes. Paste JSON and get equivalent YAML with proper two-space indentation, quoted strings where needed, and block-style arrays.
Worked example
{"name": "Ada", "tags": ["a", "b"]} becomes:
name: Ada
tags:
- a
- b
Notes
JSON is technically valid YAML, so any JSON parses as YAML too. Conversion goes one way here; the result drops JSON-only quirks like trailing commas. Related tool: the JSON Formatter & Validator for checking JSON first.
Planning estimate only. Results use the list prices shown and may differ from your actual bill. Terms
Frequently asked questions
Is YAML better than JSON for configs?
For hand-edited configs, usually yes: comments, no mandatory quotes or commas, and cleaner nesting. For machine-to-machine data, JSON's strictness wins.
Will my data survive the conversion?
Yes for standard JSON: objects, arrays, strings, numbers, booleans and null map directly to YAML equivalents.
Why does YAML care about indentation?
Indentation defines structure in YAML, like Python. This tool emits consistent two-space indentation so the output parses correctly.
Is my JSON sent to a server?
No. Conversion happens locally in your browser, so config data with secrets stays private.
