How ZeroData protects your privacy

  • ✓ No Uploads: Processing happens entirely via client-side JavaScript.
  • ✓ No Storage: We do not have a database. We physically cannot save your data.
  • ✓ No Tracking: We don't log what you process or track your inputs.
  • ✓ Verifiable: Check your DevTools Network tab. You will see 0 outbound requests.

Stop Uploading Your API Keys

A `.env` file is the heart of your application's configuration. It holds your database credentials, AWS access keys, Stripe secrets, and internal tokens. Over time, as multiple developers add new features, this file usually becomes a chaotic, unreadable mess of random keys.

You might be tempted to paste it into a random online text formatter to sort the lines or align the equals signs. Do not do this. Many online text tools log user inputs, and pasting your production secrets into an untrusted server is a massive security risk.

Our ENV File Formatter was built specifically to solve this. It parses your configuration, aligns the values into neat columns, and optionally sorts the keys alphabetically—all entirely within your local browser memory.

Because we are a ZeroData platform, your secrets never touch a server. You get the readability of a perfectly formatted config file with the absolute security of a local, air-gapped utility.

Need to convert your .env file to JSON for a serverless platform? Use our ENV to JSON Converter for instant bidirectional conversion. Also read why uploading .env files online is dangerous.

Common Use Cases

  • Cleaning up messy local .env files where keys are added randomly over time.
  • Alphabetizing environment variables to quickly compare configurations between environments.
  • Standardizing .env.example files before committing them to GitHub repositories.
  • Making extremely large configurations readable by visually aligning the assignment operators.

Frequently Asked Questions

What does this ENV file formatter do?

It parses your raw .env file contents and neatly aligns the equals (=) signs so the values form a clean column. Optionally, it can sort your environment variables alphabetically by key, which is incredibly useful for finding specific config flags in large environments.

Are my API keys and database passwords safe?

Absolutely. The formatting logic is written entirely in JavaScript and runs locally in your browser. We do not have a backend server for this tool, and your secrets are never transmitted anywhere.

Does it delete comments or empty lines?

If you simply use the 'Format' feature, it perfectly preserves all your `# comments` and empty lines while aligning the variables. However, if you choose the 'Sort Alphabetically' option, it will strip out comments to provide a clean, alphabetical list of pure key-value pairs.

What happens to invalid lines?

If the tool detects a line without an equals sign that isn't a comment, it safely comments it out (e.g., `# Invalid: your-string`) so you don't accidentally lose data.
