Convert flat JSON objects to .env environment variables. JSON to .env is a free online tool from the ToolsRift JSON Tools collection. It runs entirely in your browser — nothing to install, no signup, and your data never leaves your device.
Paste a flat JSON object and copy the resulting KEY=value lines straight into your .env file.
Each top-level key becomes an environment variable name, typically upper-cased with dots or dashes turned into underscores.
Values containing spaces or special characters are wrapped in quotes so the .env line parses correctly.
Flatten nested JSON first — .env files are flat key-value pairs and cannot represent nested structures directly.
