How to use the ENV to JSON Converter
Convert .env to JSON in 3 steps:
1
Paste your .env content
Paste KEY=VALUE pairs from your .env file. Comments (# lines) and blank lines are ignored automatically.
2
Configure type detection
Toggle 'Auto-detect types' to convert numeric strings to numbers and 'true'/'false' to booleans. Leave off to keep all values as strings (dotenv default behavior).
3
Click Convert and copy
Get a clean JSON object. Copy to clipboard or download as a .json file.
When to use this tool
Use ENV to JSON Converter when you need to:
- →Convert a .env file to JSON for use in a configuration management system that consumes JSON
- →Share environment variable sets with teammates as a readable, structured JSON object
- →Process .env files in a build script or CLI tool that works with JSON input
- →Convert environment variables exported from a CI/CD platform (GitHub Actions, Vercel) to JSON
- →Inspect and validate a .env file structure by viewing it as a clean JSON object
Frequently asked questions
Q:Are .env comments handled?
Yes. Lines beginning with # are treated as comments and omitted from the JSON output. Inline comments (KEY=value # comment) are not currently stripped — the # and everything after it becomes part of the value. Place comments on their own lines for reliable results.
Q:Are quoted values supported?
Yes. Values wrapped in single quotes ('value') or double quotes ("value") have the surrounding quotes stripped in the output. For example, APP_NAME="My App" becomes { APP_NAME: "My App" } — the quotes are removed and the inner value is used as-is.
Q:How are data types handled in the JSON output?
With 'Auto-detect types' enabled: numeric strings (PORT=3000) become JSON numbers, 'true' and 'false' become JSON booleans, and empty values become null. With auto-detection off, all values are output as JSON strings — this matches standard dotenv behavior where everything is a string.
Q:Are multiline .env values supported?
Values that span multiple lines using a quoted newline (CERT="-----BEGIN CERTIFICATE-----\n...") are supported. The \n escape sequences are preserved in the JSON string output as literal newline characters, matching how dotenv libraries parse them at runtime.
Q:Should I include sensitive values like passwords or API keys?
This tool processes your .env content entirely in the browser — no data is sent to a server. That said, be cautious about pasting real production secrets into any web tool. Consider replacing sensitive values with placeholder text before converting, especially on shared or public computers.
Q:What's the difference between ENV to JSON and ENV to JSON with type coercion?
Without type coercion (the dotenv default), every value in the JSON output is a string — PORT=3000 becomes { PORT: '3000' } and DEBUG=false becomes { DEBUG: 'false' }. With coercion enabled, PORT becomes the number 3000 and DEBUG becomes the boolean false. Use coercion when your consuming code expects typed values rather than strings.
