Convert JSON objects to .env file format
All processing happens in your browser. No data is sent to any server.
Quote All Values
Sort Keys
Paste a flat JSON object above to convert it to .env format. Nested objects and arrays will be skipped with a warning.
Why This Tool
When your configuration lives in a JSON file or API response and you need to create a .env file for local development, Docker, or CI/CD, this tool converts flat JSON objects to KEY=VALUE format. Nested keys are flattened using dot or underscore notation.
How It Works
Paste your JSON object into the input area. The tool maps each key-value pair to ENV format, properly quoting values that contain spaces or special characters. Nested objects are flattened with configurable separators. Download the result as a .env file.
