About the .env to JSON Converter

The ByteTools .env to JSON Converter parses dotenv files — the KEY=value format used by Node.js, Docker, Laravel, Rails and virtually every modern framework — into a clean JSON object, and converts JSON back into a correctly quoted .env file.

The parser understands the details that trip up naive converters: optional export prefixes, single-quoted values kept literal, double-quoted values with \n and \t escapes, values spanning multiple lines inside quotes, full-line and trailing # comments, and duplicate keys where the last one wins. Going the other way, values containing spaces, quotes or newlines are re-quoted so the file loads correctly.

Because .env files hold API keys and database passwords, privacy matters: this tool runs 100% locally in your browser and your variables are never transmitted, logged or stored anywhere.

Frequently asked questions

Is it safe to paste a .env file with real secrets?

The conversion happens entirely in your browser with JavaScript — nothing is uploaded, logged or stored on any server, and the page works offline. That said, general hygiene applies: avoid pasting production secrets into any shared or recorded screen.

What is the difference between single and double quotes in .env files?

Double-quoted values expand escape sequences, so "line1\nline2" contains a real newline. Single-quoted values are literal — '$HOME' stays exactly those characters. The parser follows both rules, matching the behaviour of the dotenv libraries.

How are comments handled?

Lines starting with # are skipped entirely, and in unquoted values a # preceded by whitespace starts a trailing comment that is cut off. A # inside quotes is kept, because it is part of the value.

Are values converted to numbers or booleans in the JSON?

No. Environment variables are always strings at runtime — process.env.PORT is "3000", not 3000 — so the JSON keeps every value as a string to represent exactly what your application will receive.

Can I convert JSON back into a .env file?

Yes. Switch the direction to JSON → .env and each top-level key becomes a KEY=value line. Values with spaces, quotes, # or newlines are automatically double-quoted and escaped so the generated file parses correctly.
