JSON to ENV
Convert JSON objects to .env file format (KEY=value). Supports nested objects with underscore-separated keys, arrays as comma-separated values, optional key prefix, and value quoting.
How to Use JSON to ENV
The JSON to ENV Converter transforms JSON objects into .env file format. Paste a JSON object and get KEY=value pairs instantly. Nested objects are flattened with underscore-separated keys (e.g., database.host becomes DATABASE_HOST). Arrays become comma-separated values. Optionally add a prefix to all keys (e.g., APP_) and toggle value quoting. Perfect for converting API config responses into environment variable files for Docker, Node.js, or any application that reads .env files.
Step-by-Step Instructions
- Paste your JSON object into the input area
- Optionally set a key prefix (e.g., APP)
- Toggle quote values if needed
- Copy the generated .env output
