JSON to ENV File Converter
Convert a JSON object into dotenv style KEY equals value lines, ready to drop into a .env file for local development or a deploy config. This is the fast way to turn a settings object or a secrets blob into environment variables without renaming every key by hand. This tool reads your JSON object, upper cases each key and replaces characters that are not allowed in env names with underscores, then writes one line per pair. Values that contain spaces, quotes or special characters are wrapped in double quotes and escaped so the file parses correctly, while nested objects are flattened into underscore joined keys so nothing is lost. Booleans and numbers are stringified as is. Paste your JSON, click convert, and copy the env lines. Everything runs locally in your browser, so your secrets never leave your machine.
