About Env Variable Parser

Move configuration between formats without retyping it. Paste a .env file, JSON object or YAML document, and the tool detects the format and shows the same variables in all three, ready to copy or download. It also flags values that look like secrets, such as API keys and passwords, so you do not commit them by mistake. Because it all happens in your browser, your secrets never leave your machine.
