How to use .env ↔ JSON Converter
The .env ↔ JSON Converter transforms dotenv configuration files into JSON and back, instantly in your browser. Paste a .env file and get a clean JSON object of every key and value, with quoted values unwrapped, comment lines ignored, and export prefixes stripped. Switch direction to turn a JSON object into a valid .env file, automatically re-quoting any value that contains spaces or special characters. It is a fast, private way to migrate configuration between formats without pasting secrets into an online service.
- Select ".env → JSON" to parse a dotenv file, or "JSON → .env" to generate one.
- Paste your .env file or JSON object into the input area.
- Comment lines and export prefixes are stripped automatically when parsing.
- Review the converted JSON or .env output in the result panel.
- Copy the result for use in your project or deployment configuration.
Your data never leaves your device — 100% private processing.
What the dotenv format looks like
A .env file is a simple list of KEY=value lines used to supply environment variables to an application, popularised by the dotenv library family across Node.js, Python, Ruby and many frameworks. Lines beginning with # are comments and are ignored. Values may optionally be wrapped in single or double quotes, which is how you include leading or trailing spaces or characters that would otherwise be ambiguous. Some files prefix lines with the shell keyword export so the same file can be sourced directly in a terminal. This converter understands all of these conventions, stripping comments and export prefixes and unwrapping quotes so the resulting JSON contains just the clean key-value data.
| Input line | Parsed key | Parsed value |
|---|---|---|
| DB_HOST=localhost | DB_HOST | localhost |
| export PORT=3000 | PORT | 3000 |
| NAME="my app" | NAME | my app |
| # a comment | (ignored) | (ignored) |
When to quote values
When converting JSON back to a .env file, the converter decides whether each value needs quoting. A plain value such as 3000 or localhost can be written bare, but a value containing spaces, a hash, a quote or an equals sign must be wrapped in double quotes so a dotenv parser reads it correctly. Empty values are also quoted to make the intent explicit. Any embedded double quotes are escaped with a backslash. This mirrors how robust dotenv libraries serialise values and ensures the file you generate can be parsed back without surprises. Keep in mind that .env files are plain text — never commit real secrets to version control, and prefer a secrets manager for production credentials.
Worked examples
Parse a .env file
Inputs: export DB_HOST=localhost NAME="my app"
Result: { "DB_HOST": "localhost", "NAME": "my app" }
Build a .env file
Inputs: { "PORT": 3000, "MSG": "hi there" }
Result: PORT=3000 MSG="hi there"
Glossary
- dotenv
- A convention and library family for loading KEY=value pairs from a .env file into a program’s environment variables.
- Environment variable
- A named value supplied to a process by its environment, commonly used for configuration and secrets.
- export prefix
- The shell keyword placed before a variable assignment so a .env file can also be sourced in a terminal.
- Quoted value
- A value wrapped in single or double quotes to preserve spaces or special characters.
- Comment line
- A line beginning with # that is ignored by dotenv parsers and this converter.
