About JSON to ENV Converter

This tool allows you to convert JSON data into environment variables, Docker .env files, or YAML configurations. Perfect for setting up configuration for Docker containers, Kubernetes deployments, or any application that uses environment variables.

How it works: The converter parses JSON objects and arrays, flattens hierarchical structures using customizable separators, then transforms them into environment variable format or YAML configurations following platform-specific conventions and naming standards.

Features:

  • Multiple output formats: Convert to Docker .env format or various YAML formats
  • YAML subformats: Support for Docker, Compose, Kubernetes, and Azure App Settings formats
  • Custom separators: Use colon (:) or underscores (__) as separators for nested keys
  • Case preservation: Choose whether to preserve original key case or convert to uppercase
  • Automatic nesting: Hierarchical JSON objects are automatically flattened with the selected separator

Learn more about environment variables at Wikipedia Environment Variables and configuration management at The Twelve-Factor App Config.

JSON values will be automatically escaped according to the selected output format conventions. All conversion is performed locally in your browser.

Technical Standards & Configuration Best Practices

Environment Variable Standards & Conventions

Following established conventions for environment variable naming and structure ensures consistency, maintainability, and compatibility across different platforms.

Naming Conventions:
  • SCREAMING_SNAKE_CASE for variable names
  • Hierarchical prefixes for organization (APP_DB_HOST)
  • Standardized suffixes for data types
  • Platform-specific variable name patterns
YAML Format Specifications & Compliance

YAML configuration files must adhere to specification standards and platform-specific schemas for optimal compatibility and validation.

Format Standards:
  • YAML 1.2 specification compliance
  • Docker Compose schema validation
  • Kubernetes resource specifications
  • Azure ARM template compatibility
Security & Configuration Management

Proper configuration management requires understanding of security implications, secret handling, and environment isolation to prevent configuration drift and vulnerabilities.

Security Considerations:
Secret managementEnvironment isolationAccess controlAudit loggingConfiguration driftEncryption at rest

Security Warning: Never store sensitive data like passwords, API keys, or certificates in plain text environment files. Use dedicated secret management solutions.
