.env Parser

Convert environment variables into structured formats.

Runs locally in your browser. No uploads.

Parse .env to JSON/YAML (dotenv-compatible)

This .env parser converts KEY=VALUE pairs into JSON or YAML directly in your browser. It supports export KEY=VALUE, quoted values (single/double), multiline values, and unquoted inline # comments. Sensitive keys are highlighted and you can mask values for safer viewing.

After exporting, verify your JSON with JSON Validator and validate YAML with YAML Formatter & Validator. If you need structure/validation for configs, generate a JSON schema with JSON Schema Generator.

Copy/export safely, mask sensitive values, and spot duplicates or invalid keys.

Tip: after exporting JSON, verify it in JSON Validator and format it in JSON Formatter.

Examples:

Parses automatically as you type. Supports export KEY=value, quoted values, multiline values, and inline # comments for unquoted values (comment starts when `#` appears after whitespace, e.g. KEY=VAL # comment).

Privacy, safety, and limitations

  • No uploads: parsing happens locally in your browser.
  • Masking helps prevent accidental screen sharing leaks (copy still works when you need it).
  • Dotenv behavior differs slightly across runtimes; if you rely on a specific library, double-check edge cases (especially complex quoting).
  • For more details on how privacy is handled, see Privacy Policy.

Workflow guides

Step-by-step chains that connect related tools for common tasks.

Migrate .env variables to a structured config format

  1. Paste your .env file contents (use dummy values for any real secrets) into the input field.
  2. Copy the JSON output and validate that all expected variables are present and correctly parsed.
  3. Parse and inspect cookie strings alongside auth tokens with Cookie Parser if your .env includes session or auth cookie values.

Frequently Asked Questions

What is a .env file and how is it parsed?

A .env file stores environment variables as KEY=VALUE pairs, one per line. Lines starting with # are comments; blank lines are ignored. Values can be quoted (single or double) to preserve whitespace or special characters. This parser extracts all variables and outputs them as structured JSON or as an object you can inspect and copy.

Are my .env variables safe to paste here?

This tool runs entirely in your browser — your environment variables never leave your device. However, treat .env files as sensitive data: they typically contain database credentials, API secrets, and auth tokens. Use placeholder values when testing or demonstrating, and never commit real .env files to version control.

How does the parser handle variable expansion?

Basic variable expansion (VAR=$OTHER_VAR or VAR=${OTHER_VAR}) is resolved when the referenced variable appears earlier in the file. Circular references are flagged. The output shows both the raw value and the expanded value so you can verify interpolation is working as expected.

Can I convert .env variables to a different config format?

Yes. The parser outputs JSON by default, which you can reformat as YAML, TOML, or any other config format. This is useful when migrating from .env files to a secret manager, Kubernetes secrets, or a CI/CD environment variable store that expects JSON or YAML input.
