YAML to Java Properties Converter

Transform any YAML configuration into a standard .properties file. Nested keys are joined with dots, values are properly escaped for Java Properties format compliance. Arrays use bracket notation (key[0], key[1]), compatible with Spring Boot @ConfigurationProperties binding.

Use Cases

• Spring Boot Applications — Convert YAML application.yml to application.properties format
• Legacy Java Systems — Bridge modern YAML config with Java property files
• Microservices — Generate config files for Java-based services from YAML source
• DevOps Pipelines — Transform YAML-based infrastructure config into Java properties

Example

Input (YAML):

app:
  name: MyApp
  version: "1.0.0"
  servers:
    - 192.168.1.1
    - 192.168.1.2
  database:
    url: jdbc:postgresql://localhost:5432/mydb
    pool:
      maxActive: 10

Output (Java Properties):

app.name=MyApp
app.version=1.0.0
app.servers[0]=192.168.1.1
app.servers[1]=192.168.1.2
app.database.url=jdbc:postgresql://localhost:5432/mydb
app.database.pool.maxActive=10
