Developers often receive configuration as JSON, then need to split those values back into environment variables for a local app, CI job, or container runtime. Converting the data into KEY=value lines is faster than rewriting each setting by hand.
What Is the JSON to .env?
JSON to .env is one of the tools in WebdevToolbox’s JSON Tools category. Convert JSON data to .env / properties style KEY=value lines. It runs entirely in your browser — no server uploads, no accounts, no waiting.
How to Use It
- Open the tool at /tools/json-to-env.
- Paste your JSON configuration data into the input field.
- Review the generated .env or properties-style KEY=value lines as they update in real time.
- Use the Copy button to copy the output into your environment file.
Key Features
- 100% client-side — all processing happens in your browser. Nothing is sent to a server.
- Real-time conversion — the KEY=value output updates immediately as you edit the JSON input.
- Environment-file output — generate .env or properties-style lines from structured config data without manual rewriting.
- Config migration helper — use JSON exports as a bridge when moving settings into local development or deployment environments.
- One-click copy — copy the generated lines to your clipboard with a single button press.
When to Use the JSON to .env
- Local setup — turn a JSON config blob into a .env file for a Node.js, Python, or PHP application.
- Container configuration — prepare environment variable lines from structured settings before wiring them into Docker or Compose.
- CI secrets mapping — convert non-secret JSON defaults into KEY=value entries for build pipelines and staging environments.
