YAML ↔ JSON Converter

Paste YAML (Kubernetes manifests, CI configs, docker-compose files) and get equivalent JSON — or go the other way. Powered by a real YAML parser running locally, so config files with secrets never leave your device.

Examples

Input

name: Ada
skills:
  - math
  - code

Output

{
  "name": "Ada",
  "skills": ["math", "code"]
}

How to use YAML ↔ JSON Converter

Paste your config

Drop in YAML (or JSON) — Kubernetes manifests, docker-compose, GitHub Actions, anything.

Pick a direction

YAML → JSON or JSON → YAML with one toggle.

Fix any errors

If the input is invalid, we show the parser’s error message so you can correct it.

Copy the result

Copy or download the converted file.

Why use this tool

Real YAML 1.2 parser (js-yaml) — not a regex approximation

Both directions: YAML → JSON and JSON → YAML

Clear error messages with the failing line

Config files with secrets stay on your device — nothing is uploaded

Frequently asked questions

Is it safe to paste configs that contain secrets?

Conversion happens entirely in your browser — nothing is transmitted or stored. Still, rotate any secret you believe may have been exposed elsewhere.

Which YAML features are supported?

Standard YAML 1.2: nested maps and lists, multi-line strings, anchors and aliases, and multiple documents (the first document is converted).

Why did my YAML fail to parse?

YAML is indentation-sensitive. The error message shows the line and reason — the most common causes are mixed tabs/spaces and misaligned nesting.
