This runs entirely in your browser and nothing is uploaded — but treat any secret you paste into any web tool as exposed, and rotate it.

Quick Tool Overview

The ENV to JSON converter reads a .env file properly: export prefixes, all three quoting styles, escape sequences and comments that must not be stripped from inside a quoted value — with optional nesting of underscored keys.

About the ENV to JSON

A .env file is a flat list of key-value pairs with just enough syntax to be annoying: optional export prefixes, three quoting styles, escape sequences inside double quotes, and comments that must not be stripped from inside a quoted value.

This converter handles all of that and gives you JSON. There is also an optional unflatten step that turns DB_HOST and DB_PORT into a nested db object, which is what you want when the destination is a config file rather than an environment. Because it runs entirely in your browser, pasting a file that contains real credentials does not send them anywhere — but the usual advice still applies: rotate anything you paste into a tool you did not write.

Key features of the ENV to JSON

Real dotenv syntax

Export prefixes, double, single and unquoted values, and escape sequences inside double quotes are all handled the way a loader handles them.

Optional nesting

Split keys on underscores so DB_HOST and DB_PORT become a db object — what you want when generating a config file.

Strings by default

Every environment variable really is a string, so no typing happens unless you ask for it.

Comments handled correctly

A hash inside a quoted value is content, not a comment, which is where naive parsers truncate a password.

Nothing leaves the tab

The conversion runs in your browser — though any secret pasted into any web tool is worth rotating regardless.

How to use the ENV to JSON

  1. 1

    Paste your .env file

    The whole file, comments and all.

  2. 2

    Choose the nesting

    Keep flat keys, or split on underscores to build a nested object.

  3. 3

    Choose type handling

    Values are strings by default, as they are in a real environment. Turn on typing to get numbers and booleans.

  4. 4

    Copy the JSON

    Ready for a config file, a test fixture or a deployment template.

Frequently asked questions

The conversion happens entirely in your browser and nothing is sent anywhere. Even so, treat any secret you paste into any web tool as exposed and rotate it.
