How do I convert a .env file to JSON?

Paste the file into the input box and the JSON appears instantly on the right. A line like DATABASE_URL=postgres://app:pw@db:5432/api becomes {"DATABASE_URL": "postgres://app:pw@db:5432/api"}. Full-line # comments and blank lines are dropped, and an = inside the value is kept, so a connection string with ?sslmode=require survives intact. Click copy to grab the result.

What happens to the export prefix and quoted values?

The export prefix is stripped, so export API_KEY=abc parses the same as API_KEY=abc. Double-quoted values expand escapes, so GREETING="hi\nthere" becomes a two-line string, while single-quoted values are treated literally with no escape expansion. After the closing quote, a trailing # comment is ignored. This matches how Node dotenv and Bash read the file.

How does it handle an = sign or a

Only the first = on a line splits key from value, so TOKEN=ab=cd=ef keeps the value ab=cd=ef. For comments, an inline comment needs a space before the #, so PORT=3000 # http port gives 3000, but COLOR=#ff0000 keeps the full hex value because there is no space before the hash. Quoted values are never cut by a # inside the quotes.

How do I convert JSON back into a .env file?

Switch the direction to JSON to .env and paste a flat object like {"PORT": 3000, "APP_NAME": "My App"}. You get PORT=3000 and APP_NAME="My App" back. Numbers and booleans are written without quotes, values with spaces or special characters are double-quoted and escaped, and a nested object or array is JSON-stringified into one quoted value rather than silently dropped.

Should I turn on type inference?

Turn it on when the JSON consumer expects real types: PORT=3000 becomes the number 3000 and DEBUG=true becomes the boolean true. Leave it off when every value must stay a string, which is how process.env actually behaves at runtime. The tool is deliberately conservative: it keeps leading-zero values like 01234 and codes like 08 as strings, since those are usually IDs you do not want turned into numbers.

Load secrets from .env into a JSON-config app

Your old service reads a flat config.json, but the rest of your stack standardized on .env files. Paste the .env, copy the JSON, and drop it into the legacy app without hand-typing thirty keys. The = inside connection strings and the quoted multi-word values come through exactly as written, so you do not chase a broken DATABASE_URL later.

Generate a .env from a JSON settings export

A dashboard or CI system hands you settings as a JSON blob, but your deploy expects a .env. Switch to JSON to .env, paste the object, and get KEY=value lines with the right quoting: a value with spaces gets wrapped in quotes, a number stays a bare number. Paste the output into your .env file and ship.

Inspect a messy .env as structured data

When a .env grows past fifty lines with mixed quoting, comments, and export prefixes, it is hard to eyeball. Convert it to JSON to see the real parsed keys and values, side by side, free of comments and formatting noise. The key count tells you instantly whether a duplicate quietly overrode something.

Feed environment config into a script or test fixture

You need the same variables your app reads, but as a JSON object a test or a Node script can import directly. Convert the .env once, save the JSON as a fixture, and your tests run against the exact same values without parsing dotenv at runtime. Type inference makes PORT a number so numeric assertions just work.

What this tool does

Free two-way converter between .env (dotenv) files and flat JSON. Paste a .env and get a clean JSON object; paste a JSON object and get a valid .env back. The parser handles the real-world dotenv dialect that trips up naive splitters: KEY=value pairs, full-line and inline # comments, single and double quoted values (with \n \t escapes inside double quotes), the optional export prefix, blank lines, and = signs that appear inside the value such as a database URL with a query string. Turn on type inference and PORT=3000 becomes a real number and DEBUG=true becomes a real boolean, while leading-zero strings like an account ID stay text. Going the other way, values that contain spaces or special characters are quoted and escaped so the .env round-trips cleanly. One-click copy and a shareable URL that reopens the same conversion. 100% client-side, nothing uploaded.

Real-world use cases

Load secrets from .env into a JSON-config app

Type inference makes PORT a number so numeric assertions just work.

Common pitfalls

Expecting numbers and booleans without turning on type inference. By default every value stays a string, because that is how process.env behaves at runtime. If your code does config.PORT + 1 and gets "30001", flip on type inference so PORT comes through as the number 3000.
Forgetting that an inline comment needs a space before the
Pasting a nested JSON object and expecting a tidy .env. A .env file is flat key=value only. Nested objects and arrays get JSON-stringified into a single quoted value rather than expanded, so flatten your JSON first (or accept the stringified blob) before converting to .env.

Privacy

Every step, parsing the .env, expanding quotes and escapes, inferring types, and flattening JSON back to dotenv, runs as plain JavaScript inside your browser tab. No file, key or secret is uploaded or logged. The one caveat: the shareable link encodes your input and options in the query string, so a link pasted into chat records that text in the recipient server's access log. A .env almost always holds real credentials, so for anything live, use the copy button and paste the text rather than sharing the URL, and never put a real API key into a public share link.
