Конвертер ENV у JSON

A two-way converter between .env files and JSON. Turn a .env file into a JSON object to inspect or edit it, or turn JSON back into a valid .env file, handling comments, the export prefix and quoted values.

Converting to JSON is useful for bulk-editing config, diffing two environments, or feeding settings into a tool that expects JSON; converting back produces a ready-to-use .env.

Because .env files hold secrets, privacy matters: the conversion runs entirely in your browser, so your environment variables and any keys in them never leave your device.

A .env file is the simple KEY=value list that apps load to configure themselves, database URLs, API keys, feature flags, kept out of the code and out of version control. It is the standard way to separate configuration from an application.

When reading a .env, comment lines starting with # and blank lines are ignored, an optional export prefix is removed, and surrounding quotes are stripped from values, so the JSON you get is clean and exactly the key-value pairs.

When writing a .env, values that contain spaces or special characters are wrapped in double quotes so they parse correctly in a shell or a dotenv loader, which avoids a common source of broken configuration.
