About ENV File Parser
Convert .env files to JSON objects and vice versa. Paste a .env file to see all variables in a clean key-value table with types detected, or paste a JSON object to generate the .env format. Handles quoted values (single and double), inline comments, empty values, multiline values, and special characters. Useful for debugging, auditing, and migrating environment configs.
All processing happens entirely in your browser using modern web APIs. Nothing is uploaded to our servers — your data stays local and private. Free to use forever, with a Pro plan for power users who want an ad-free experience and API access.
Common use cases
- Auditing all environment variables in a .env file at a glance
- Converting environment variables to JSON for configuration management
- Generating a .env file from a JSON object for quick setup
- Checking for duplicate keys or missing values in a .env file
- Migrating config from .env format to a JSON config file or vice versa
How it works
Parses each non-empty, non-comment line of the .env file using a regex that handles KEY=VALUE, KEY="value with spaces", KEY='single quoted', and KEY= (empty value). Comments starting with # are stripped. The JSON-to-ENV direction uses Object.entries() to serialize back to KEY=value lines, adding quotes when the value contains spaces or special characters.
