Convertir .env files to JSON
.env fichiers stocker KEY=VALUE pairs pour environment configuration. Convertir en JSON pour structured access, type casting, et validation.

.env files contain KEY=VALUE pairs, one per line, with optional comments (#) and quotes. They are used for environment-specific configuration (database URLs, API keys, feature flags). Converting to JSON enables type casting, nesting, and schema validation.
- 2 Convertisseur TOML →
Analyser the .env file as key=value pairs and convert to JSON. Each line becomes a top-level key. Quoted values are strings; unquoted numeric values are cast to numbers; true/false are cast to booleans.
- 3 Formateur JSON →
Formater the converted JSON. .env files are flat (no nesting), so the JSON will be a flat object. If you need nesting (e.g., DATABASE_HOST, DATABASE_PORT → database: {host, port}), post-process the JSON with a naming convention parser.

Security: .env files must never be committed to version control (add to .gitignore). They often contain secrets (API keys, database passwords). Converting to JSON does not change this — the JSON file must also be gitignored. Use a secrets manager (Vault, AWS Secrets Manager) for production.
Questions fréquentes
- Should I use .env or JSON for configuration?
- Use .env for deployment-specific values (secrets, URLs) that differ between environments. Use JSON or TOML for structured configuration (feature flags, UI settings) that benefits from nesting and types. They serve different purposes and can coexist.
- How do I handle multiline values in .env?
- Use quotes: KEY="line1\nline2". Some .env parsers support this, others do not. If you need multiline values, consider JSON or YAML instead. The conversion tool will handle quoted multiline values correctly.
