Usage examples

Case 1 · Plain YAML map

DATABASE_URL=postgres://...
PORT=3000

DATABASE_URL: "postgres://..."
PORT: 3000
DEBUG: true

Case 2 · docker-compose

NODE_ENV=production
PORT=3000

services:
  app:
    environment:
      NODE_ENV: production
      PORT: 3000

Case 3 · GitHub Actions

NODE_ENV=production
LOG_LEVEL=info

jobs:
  app:
    runs-on: ubuntu-latest
    env:
      NODE_ENV: production
      LOG_LEVEL: info

When to use this tool

→Promoting local .env to a GitHub Actions workflow env block
→Filling out docker-compose.yml without retyping keys
→Generating Ansible / Chef / SaltStack vars from existing .env
→Converting to Helm values.yaml for a Kubernetes deploy

Common mistakes

⚠Pasting into a YAML file that already has a key of the same name — causes silent overrides
⚠Forgetting YAML is indentation-sensitive — don't manually edit the indentation
⚠Shipping secrets in GitHub Actions YAML to a public repo (use GitHub Secrets instead)
⚠Assuming quoted YAML strings will match your app's type coercion — test with your actual parser

Convert .env to YAML Online

Paste a .env and get YAML back — formatted for plain YAML maps, docker-compose environment blocks, GitHub Actions env: blocks, or Ansible vars files. Useful when migrating config from a local .env to infra-as-code.
