About ENV to JSON Converter

This tool converts standard .env files into JSON instantly. It is useful when you want to inspect environment variables in a structured format, transform config for scripts, or debug dotenv files copied from local, staging, or production environments.

The converter runs entirely in your browser. Your environment variables, API keys, and secrets are never uploaded to a server. It supports comments, quoted values, inline comments, duplicate detection, empty values, and optional smart type coercion for booleans, numbers, arrays, objects, and null.

How to Use

  1. Paste your .env file into the input box, or click Load Sample.
  2. Choose a value mode — keep everything as strings or enable smart type detection.
  3. Review duplicates and invalid lines before using the output.
  4. Copy or download the JSON for use in scripts, tests, or configuration audits.

What Smart Types Does

Booleans

true and false become JSON booleans.

Numbers

Values like 3000 or 15.5 become numbers.

JSON Values

Quoted arrays and objects such as '{"enabled":true}' are parsed into real JSON.

Common Use Cases

  • Debugging config: Inspect large dotenv files in a structured JSON view.
  • Migration work: Convert legacy .env values for scripts or tooling that expects JSON.
  • Deployment audits: Quickly review which keys are duplicated, empty, or malformed before release.
  • Fixture generation: Turn environment files into JSON blobs for local testing and mocks.

Frequently Asked Questions

Does this support comments and quoted values?

Yes. Full-line comments are ignored, inline comments after whitespace are removed, and quoted values are unwrapped before conversion.

What happens with duplicate keys?

The converter shows duplicate keys in the warning panel, and the last valid occurrence wins in the final JSON output. That matches common dotenv loading behavior.

Will this upload my secrets anywhere?

No. Everything happens locally in your browser. No request body is sent to a server.

Should I use smart types or string mode?

Use smart types when your values contain booleans, numbers, arrays, or JSON objects that you want as native JSON values. Use string mode when you want exact dotenv-style string output with no coercion.
