FAQ
How do I convert JSON to a .env file?
Paste your flat JSON object into the tool: each key is turned into an environment variable (KEY=value), and you can copy or download the generated .env file.
Are values with spaces handled correctly?
Yes, values containing spaces or special characters are automatically wrapped in quotes so they stay valid in a .env file.
Is my data sent to a server?
No, the conversion runs entirely in your browser. No data is transmitted to or stored on any server.
