FAQ
Will the tool run the JavaScript I pasted?
No. Your input is used only to produce text output; its code is not executed and no network request is sent.
Are variables and arbitrary expressions supported?
No. Expressions whose values cannot be determined safely without execution produce an unsupported-syntax error.
Can JSON.stringify be converted?
Common object or array literal forms are supported; dynamic function calls and variable dependencies are not guessed.
Will the request be sent after generation?
No, the output cURL is still just text.
