YAML ↔ JSON

Convert YAML to JSON and back, handy for Docker Compose and Home Assistant.

Input

services:
  web:
    image: nginx:alpine
    ports:
      - "8080:80"
    environment:
      TZ: Europe/Amsterdam
    restart: unless-stopped

Result

What does this mean?

YAML and JSON describe the same kind of data: lists, names with values and text. YAML is more readable for humans and is used for Docker Compose and Home Assistant; JSON is stricter and is often used by programs. Here you convert one into the other.

Comments (#) in YAML are lost when converting to JSON, because JSON does not support that. Pay attention to indentation in YAML: use spaces, not tabs.
