Usage examples

Case 1 · Basic conversion

DATABASE_URL=postgres://localhost/app
PORT=3000

{
  "DATABASE_URL": "postgres://localhost/app",
  "PORT": 3000
}

Case 2 · Type coercion on

DEBUG=true
RETRIES=5
NAME=hello

{
  "DEBUG": true,
  "RETRIES": 5,
  "NAME": "hello"
}

Case 3 · Type coercion off (literal strings)

DEBUG=true
RETRIES=5

{
  "DEBUG": "true",
  "RETRIES": "5"
}

When to use this tool

→Uploading config to a service that accepts JSON only (AWS Parameter Store, Vercel API, Netlify API)
→Generating a test fixture from a real .env
→Bootstrapping a process.env mock in unit tests
→Debugging what your app actually sees at runtime
→Feeding config into a JSON-schema validator (Zod, Ajv, JSON Schema)

Common mistakes

⚠Expecting nested keys: DB_HOST and DB_PORT stay flat — there's no magic tree conversion (use JSON→ENV flattening in reverse)
⚠Forgetting to turn off type coercion when you need string literals: PORT="3000" → 3000 by default
⚠Shipping the JSON output to the browser — it contains the same secrets as the .env
⚠Assuming the JSON is valid for docker-compose — it's not; docker-compose wants YAML

Convert .env to JSON Online

Paste a .env file and get a valid JSON object back. The env-to-json converter handles quoted values, comments, and escaped characters automatically. Optional type coercion will turn "3000" into 3000 and "true" into true, so the output matches how your runtime would read it.

When to use this

Sending env vars to a config-as-JSON service (Vercel, Netlify, AWS Parameter Store)
Generating test fixtures from real env files
Bootstrapping a process.env mock in unit tests
Debugging what your app actually sees at runtime

Frequently asked questions

Does it support nested keys from dotenv-expand style variables?

No. .env files are flat key/value pairs — the converter produces a flat JSON object. If you need nested JSON, use a key naming convention like DB__HOST and handle the nesting in application code with a library like nconf or convict.

Are numeric values converted to numbers?

With type coercion enabled (the default), values that parse as integers or floats become JSON numbers. PORT=3000 becomes 3000. Turn off coercion to get all values as strings.

Are comments included in the JSON?

No. JSON has no comment standard, so comments from your .env are dropped during conversion.

Can I round-trip back to .env from the JSON output?

Yes — use the JSON to ENV converter. Note that type coercion is not perfectly reversible: a number 3000 in JSON becomes the string 3000 in .env, which may or may not match your original quoting.
