.env Output
JSON to .env Converter
This tool converts a JSON object into a .env file, ready to paste into your project. Keys are uppercased automatically. Nested objects are flattened using underscore separators (e.g. { db: { host: 'x' } } becomes DB_HOST=x). An optional key prefix lets you namespace all variables (e.g. APP turns NAME into APP_NAME). The quote mode controls whether values are wrapped in double quotes. Everything runs in your browser — no data is uploaded.
Private & free — this tool runs entirely in your browser.
