Properties to JSON for YAML/ENV Migration

Properties → JSON → YAML / ENV Pipeline

When migrating from Java .properties to YAML (for Kubernetes) or .env (for Docker), JSON serves as a useful intermediate format that can be further converted using other DevToolbox tools.

Migration Pipeline

.properties → JSON → YAML    (for Kubernetes ConfigMaps)
.properties → JSON → .env    (for Docker containers)
.properties → JSON → TOML    (for Rust/Python projects)

Step 1: Properties to JSON

spring.datasource.url=jdbc:postgresql://db:5432/myapp
spring.datasource.username=admin
spring.datasource.password=secret
spring.redis.host=redis
spring.redis.port=6379
server.port=8080

Converts to:

{
  "spring": {
    "datasource": {
      "url": "jdbc:postgresql://db:5432/myapp",
      "username": "admin",
      "password": "secret"
    },
    "redis": {
      "host": "redis",
      "port": 6379
    }
  },
  "server": {
    "port": 8080
  }
}

Step 2: JSON to YAML (using JSON ↔ YAML tool)

spring:
  datasource:
    url: jdbc:postgresql://db:5432/myapp
    username: admin
    password: secret
  redis:
    host: redis
    port: 6379
server:
  port: 8080

Step 3: Or JSON to .env (using YAML ↔ ENV tool)

SPRING_DATASOURCE_URL=jdbc:postgresql://db:5432/myapp
SPRING_DATASOURCE_USERNAME=admin
SPRING_DATASOURCE_PASSWORD=secret
SPRING_REDIS_HOST=redis
SPRING_REDIS_PORT=6379
SERVER_PORT=8080

This multi-step conversion pipeline leverages JSON as a universal intermediate format, allowing you to use the full suite of DevToolbox converters for any source-to-target format combination.
