Q: How do I parse a .env file to JSON in Node.js?

Use the dotenv package: require('dotenv').config() loads .env into process.env. For a JSON object: const result = require('dotenv').parse(fs.readFileSync('.env', 'utf8')). Or parse manually: Object.fromEntries(fs.readFileSync('.env').toString().split('\n').filter(l => l && !l.startsWith('#')).map(l => l.split('=').map(s => s.trim()))).

Q: How do I parse a .env file to JSON in Python?

Use python-dotenv: from dotenv import dotenv_values; config = dict(dotenv_values('.env')). For a simple parser: import json; result = dict(line.split('=', 1) for line in open('.env') if line.strip() and not line.startswith('#')); print(json.dumps(result)).

.env parsing rules

How each .env line is parsed to a JSON value.

.env line	JSON output	Notes
`HOST=localhost`	`"HOST": "localhost"`	Unquoted string
`PORT=5432`	`"PORT": 5432`	Integer (type inference on)
`DEBUG=true`	`"DEBUG": true`	Boolean
`KEY=`	`"KEY": null`	Empty value → null
`MSG="hello world"`	`"MSG": "hello world"`	Quoted — spaces preserved, quotes stripped
`TAGS=["a","b"]`	`"TAGS": ["a", "b"]`	JSON array value parsed
`# comment`	—	Comment lines ignored
`export KEY=val`	`"KEY": "val"`	export prefix stripped

The parser handles all standard dotenv formats: unquoted values, double-quoted and single-quoted strings with escape sequences, inline comments (stripped), blank lines (ignored), and the optional export prefix. Values that look like JSON arrays or objects are parsed as JSON.

Type inference

Numbers, booleans, null and JSON arrays are automatically typed — not everything is a string.

Quoted value support

Both double and single quoted values with escape sequences (\n, \t, \") are handled correctly.

All .env variants

.env, .env.local, .env.production, .env.development — any KEY=VALUE file works.
