Env To Yaml

.env to YAML Converter

Convert any .env file into clean, structured YAML. Environment variable keys with underscore separators are intelligently reconstructed into nested YAML structure.

Use Cases

• Config Modernization — Move from flat .env files to structured YAML config
• Cross-Platform Config — Bridge environment-based config into YAML-native toolchains
• Documentation — Generate readable YAML from flat environment variable files
• Migration — Convert legacy dotenv configs to YAML-based configuration

Example

Input (.env):

DATABASE_HOST="localhost"
DATABASE_PORT="5432"
DATABASE_POOL_MAXACTIVE="10"
APP_NAME="MyApp"
APP_DEBUG="true"

Output (YAML):

database:
  host: localhost
  port: "5432"
  pool:
    maxActive: "10"
app:
  name: MyApp
  debug: "true"
