Put this on your own site

The frame below runs the same code as this page, in the reader's own browser. Nothing is sent to us, and nothing is sent to you.

AccentBackground

Pick a dark background and the text and panels follow it, so the frame stays readable on a dark page.

How it works

Lines split at the first unquoted equals sign, whitespace is trimmed, comments outside quotes are ignored, and quoted values are unwrapped. The result is a map and does not mutate process environment variables.

First-equals parsing keeps equals signs inside values.
Quote handling matches common development .env conventions.

Worked example

Parse .env file

Extract environment variables into structured JSON

Input

											# Database
DB_HOST=localhost
DB_PORT=5432
DB_NAME="myapp"

Output

												Count: 3
Comments: 1
Keys: DB_HOST, DB_PORT, DB_NAME

VARIABLES
Db host: localhost
Db port: 5432
Db name: myapp

When to use this

Node apps, CI previews, and local development setups parse .env files.

Edge cases

A password containing equals keeps text after the first separator.
A hash inside quoted text is value data.
An export prefix can be syntax or part of the key by parser mode.
