.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": "" | Empty value → empty string (same as dotenv) |
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 |
Multi-line values, export and other dotenv rules
The parser follows the same rules as dotenv: an optional export prefix is ignored, values in double, single or backtick quotes can span several lines, # starts a comment only outside quotes, and an empty value (KEY=) becomes an empty string. Numbers with leading zeros stay strings.
Other config formats: INI to JSON, TOML to JSON and YAML to JSON. To go back, use JSON to .env.
All data & config formats tools
.env parsed in your
browser. No upload.
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.
