Secure .env to JSON Conversion in Your Browser

Modern cloud and serverless platforms — including AWS Lambda, Vercel, Netlify, and Google Cloud Functions — often require environment variables in JSON format rather than the traditional .env file format. Converting between the two manually is tedious and error-prone, especially when dealing with quoted values, multiline strings, or dozens of configuration variables. This converter handles the transformation instantly and entirely in your browser.

Need to clean up or sort your .env file first? Use our ENV File Formatter to organize, deduplicate, and align your environment variables before converting.

Why Convert .env Files Locally?

Your .env file contains your application's most sensitive secrets — database connection strings, API keys, SMTP credentials, and encryption salts. Uploading these to a third-party conversion tool exposes every credential to a remote server you do not control. This converter processes everything locally using client-side JavaScript, so your secrets stay on your machine. Read why uploading .env files online is dangerous.

How to Use the ENV to JSON Converter

  1. Select conversion direction: ENV → JSON or JSON → ENV.
  2. Paste your .env content or JSON object into the input area.
  3. Click Convert to transform the input.
  4. Copy or download the converted output.

Common Use Cases

  • Converting .env files to JSON for serverless platform configuration (AWS Lambda, Vercel, Netlify).
  • Transforming JSON config objects back to .env format for local development.
  • Migrating environment variables between different deployment platforms.
  • Validating .env file structure by round-tripping through JSON and back.

Frequently Asked Questions

How do I convert a .env file to JSON?

Paste your .env content into the input area and click Convert. The tool parses KEY=VALUE pairs, ignores comments and empty lines, strips surrounding quotes, and outputs a clean JSON object.

Can I convert JSON back to .env format?

Yes. Toggle to JSON → ENV mode, paste your JSON object, and the tool outputs standard KEY=VALUE lines. Values containing spaces, equals signs, or hash characters are automatically wrapped in double quotes.

Does this tool handle comments in .env files?

Yes. Lines starting with # are treated as comments and are ignored during conversion. They will not appear in the JSON output.

Is my .env file uploaded to a server?

No. The conversion happens 100% in your browser using client-side JavaScript. Your environment variables — including database passwords, API keys, and encryption secrets — never leave your device.

What happens to quoted values?

The converter strips surrounding quotes (both single and double) from values, matching standard dotenv parser behavior. For example, API_KEY="sk-abc123" becomes API_KEY: "sk-abc123" in the JSON output.
