JSON to .env Converter

Summary

Paste a flat JSON object and instantly get the equivalent .env key=value lines.

How it works

1. Paste or type a flat JSON object into the input panel.
2. The tool parses the JSON and extracts each top-level key-value pair.
3. String values with spaces or special characters are wrapped in double quotes.
4. Boolean and numeric values are written as-is (no quotes).
5. The resulting .env lines appear in the output panel instantly.
6. Click "Copy Output" to copy the result to your clipboard.

Use cases

• Convert a config.json file into a .env file for a Node.js or Python project.
• Generate environment variable definitions from a JSON secrets export.
• Quickly migrate settings between JSON-based and dotenv-based config systems.
• Prepare .env files for Docker, Kubernetes, or CI/CD pipelines.
• Strip nested objects and flatten top-level keys before committing to a repo.
• Share environment variable templates without exposing actual secret values.
